Honestly the best car fragrance I’ve ever gotten. I’ve gotten a lot of scents in my car before but this one is top tier. Super stylish with the interior of my car and smells amazing

This makes my car smell like a bath and body works instead of like a cheap tree smell. Easy to install even though the clip vent doesn’t work on the FL5, it still magnetizes to the vents and fits perfect. Cheap mod to really changed the interior.

Great customer service, prompt delivery, well packaged product. The product itself exceeded my expectations. I ordered the JDM squash scent and it smells premium and it does not give me headaches. It smells refreshing and clean! Product is easy to use, matches any interior of my car and lasts for a long time. I highly recommend this product.

Just like how it describes, no headaches, pleasant smell, and the scent is comparable if not better than the famous air spencer squash. can last up to 2 3 months and looks real cool. I might have to get the other 3! it's a smell you wish would never end honestly.

When I put this Slate Diffuser Air Diffuser in the JDM Squash, I installed into the vent and closed my eyes. I went back in time to 2001 when I had my Firepepper red GSR slammed on bronze Buddy CluB P1s wheels with a polished lip. Sold it back in 2009 but I used to have the Squash scent 24/7 .Brought back good memories for sure and I just bought a couple of more to hand them out as Xmas Gifts .

I put the diffuser in a project 2004 Subaru WRX that has been burning oil for an unknown amount if time. When I picked the car up it smelled like a mixture of old basement must and 10w30 infused exhaust. The JDM squash scent instantly changed the entire experience of being in this car for the better!!

Store owner replied: Thanks so much, Chris! We love hearing how much JDM Squash changed the whole experience in your WRX. Really appreciate the photo and the great review!
I got the JDM Squash scent, and to me it smells pretty nice, kind of like bubblegum. There is a magnet and a clip in the back that you put right on your AC vent. It is pretty straightforward since you can just use more or less droplets if you want a heavier or lighter scent. I like it a lot!

High quality, all the way down to the packaging. The scent (JDM squash) is long lasting and pleasant. The vent-mounted slate diffuser is subtle and blends in with the car. The oil provided comes in a vial so that you can refill your diffuser multiple times when the scent fades. 12/10 I’ll have to try all the scents. Thanks again, Suma! -@GR.Dragoness

I got my Suma slate diffuser in the JDM squash scent. It smells really, really good. You just add it in, let it dissolve, clip it on, and put it on your vents.

This car diffuser is so convenient and easy to use, and the scent actually lasts. It is a simple clip that goes onto your vent and magnetizes to a little bowl where you pour your essential oils. I picked Midnight Run, which has a very natural orange wood smell that is not overwhelming. I love that I can control how much scent goes in with just a drop or two, and it does not hang in front of anyone's face.

What I love about this slate diffuser is that it attaches to the vent clip with a magnet for a nice, sleek design instead of dangling and causing a distraction. It comes with an aroma oil that you dispense right onto the slate rock, so you get to control how strong of a scent you want in your car. I got the JDM Squash scent, and it gives a citrusy, sea breeze vibe with the effect of a fizzy soda. You are also saving the environment by utilizing the slate rock.

This JDM Squash aroma oil smells so good, tropical and fruity with a pop soda type of scent. You just put a couple of drops on with the dropper and it absorbs right into the slate. Then the magnetic clip goes right onto the car vent. As a mom of four, I love having my car smell really good.

It smells really good, very clean, and lasts a while as well. The slate is magnetic and just sticks on, which is really nice. You only need a drop or two of the oil. It did seem a little expensive, but I rather enjoy it.

This smells so refreshing, literally like I just got a brand new car. I got the Midnight Run essential oil with the Suma air freshener. I just put half of the dropper in, let it really absorb, and added it to the vents.

Store owner replied: Thanks so much, Sabrina! We’re glad Midnight Run gave you that fresh, new-car feeling. We really appreciate the video review and your support!
Was skeptical about the product, how well it would sit in the air vent and if I would enjoy the fragrance! Suffice to say, it's a game changer. Love Golden Sunday. The slate absorbs and holds the oil very well. Zero seepage. I'm not into over powering scents so I only loaded about a 1/4 of the Golden Sunday essential oil onto the slate ( initial startup recommends loading half).
Shannon C. 5/5 Verified
Store owner replied: Thanks so much, Shannon! We’re glad Golden Sunday won you over and that the Slate holds the oil well with no seepage. We also love that you can keep the scent strength right where you like it. We really appreciate the thoughtful review and photo!
This little diffuser clips right onto the air vent and fills the entire car with the scent. It smells so good and delicious, giving a tropical beach relaxation vibe that is so soothing. You just have to saturate the slate, stick it on there, and then touch it up every two weeks. I am really glad I got this and I'm loving it.

This diffuser is super easy to get set up in your car with the magnetic vent clip. The aroma oil smells really good, with a lot of citrus notes that I love and kind of a soda scent. It comes with a dropper so every time you need to freshen it back up, you just add a couple drops of the oil to the slate. This will be perfect for my husband since he drives for Lyft and having a clean, nice-smelling car is super important to us.

Store owner replied: Thanks so much, Eden! We’re glad the setup was easy and that you’re loving the citrusy, soda-like scent. Sounds like a great fit for keeping the car fresh for Lyft passengers too. We really appreciate the video review!
This diffuser is extremely different from other car fresheners I have tried. It has a slate that is a magnet and attaches to the vent clip, and when you pour half a bottle of the aroma into it, the slate sucks up all the liquid. It smells really good, like soda and bubblegum. It has really made my car smell nice, especially to me and my kids.

I've been using this Sōma slate diffuser in my car, and I love the design because it looks so much more modern than traditional air fresheners. The scent goes right inside of it and the slate absorbs it. It has a magnetic attachment on the back that lets you clip it to your air vent. I got it in the scent JDM Squash, which has a really nice lemon smell and leaves my car smelling fresh.

I got this slate diffuser in the scent JDM Squash, and it smells wonderful, absolutely beautiful. The slate part magnetics right to the piece that goes inside of your car. You just put a few drops on, and it instantly absorbs onto the slate. I am absolutely loving it so far, and I cannot wait for my car to smell like this all the time!

Midnight Run smells very fancy and very deep. I get a lot of restaurant vibes from it, like walking through a hotel lobby. It comes with the little pod for the droplets and the AC clip. This is definitely one of my favorites right now, and it is going to make my car smell really good.
Jason H. 5/5 Verified
I'm a diehard sazan squash user in all my vehicles for the past 20+ years and Suma's JDM Squash scent is a very refreshing take on such an iconic scent. I'm digging the sweeter cream citrus scent it's giving off. Plus I like how much more eco friendly the product is over other older brands in the market.
Justin S. 5/5
The Suma Slate Diffuser in the scent Midnight Run smells honestly exactly like Caress Twilight. It is amazing, and I adore having it in my car. It is so easy to set up and have it smelling absolutely like cologne. I love the product!

Store owner replied: Thanks, Amelia! So glad Midnight Run is such a perfect match for you. We love that you’re enjoying the scent and easy setup!
I smoke cigarettes and don't like the smell, but this definitely works to take away the odors. I got the Sea Breeze scent and it smells super good without being too strong. You just use the dropper to soak the stone with the scent, and it connects with a magnetic hold to the vent clip. It makes my car smell fresh and I love it.

I have been absolutely loving this car air freshener diffuser. It is so pretty and sleek, and it makes my car smell so good. I have three kids and one plays sports, so getting into my car can sometimes smell from her sports bag, but this has been a game changer. It is so easy to refill and reuse by just putting a few drops on it and sticking it right into the air vent. The application is so easy and I cannot wait to get more scents.

This JDM Squash is my new favorite car air freshener because it smells like a fresh, crisp citrus soda. It is a slate diffuser that goes right on your air vent, and it is so easy to drop oil on it. The magnetic clip is very sturdy and lets you pull it on and off to add more drops, though it does take a good grip to get it off.

It filled the entire truck with scent almost immediately. The car had been off for a while, and as soon as I opened the door, I got hit with a beautiful fruity yet fresh scent. It was really simple to fill up with the product and clip into the car vent. I definitely need to keep these on hand for all my other cars, and maybe find some use for it in the house, too.

The oil smells so good. You just put a couple drops with the dropper and it absorbs right into the stone, so it is not going to leak anywhere. The magnet piece clips right on the back and then clips right on your vent. I can't wait to get back in the car tomorrow morning because it is going to smell amazing in here.

The JDM Squash scent smells amazing, and I could already smell it as soon as I opened the cap. Nothing feels cheap with the glass bottle of aroma oil, the dropper, and the magnetic piece you attach to the air vent. The instructions are very clear, and this was definitely well worth it. I am going to use this all the time and think I might get more than one.

This diffuser looks so good and is such good quality. It has a hook that goes into where the air comes out in your car and connects with a magnet, which I thought was pretty cool. The scent smells so good and very fresh, just like a perfume my husband has. It is definitely a whole experience to try, and I really enjoy it.

I got the Midnight Rush scent for this car air freshener, and it has a nice new car kind of smell. It comes with a little fragrance bottle you pour onto the stone piece, and I like being able to refill it and customize how strong the scent is. The only thing I don't like is that the magnet part is separate from the vent clip, because if you lose that piece you won't be able to use the air freshener. Overall it's nice and smells good.

I love that you can add the oil yourself to control how strong it is, and being reusable and magnetic means I can use different essential oils with it. The Japanese soda scent smells really good, more like an ambient pleasant smell rather than an obvious car freshener. It also looks great and blends right into my car's dark interior instead of looking bright and plasticky.

The Midnight Run scent is a clean new car scent, not very fruity, not very floral, just a very clean overall pleasant smell. You insert the clip, and the slate piece magnetically attaches onto it. It comes with a dropper so you simply drop the fragrance oil in the circle and it reabsorbs. This diffuser has been a wonderful addition to my car.
