First of all, I hate those tree car air fresheners. They all seem to smell awful and not last. These are in that category as well. They don't work well, unless you have the heat on high. They definitely smell better than the trees, I just wish they lasted a bit longer. This summer I didn't smell mine at all until I had to turn on the heat one cold day. It would be nice if they could smell even without air blasting through the vents.

only last a dew days and too expensive

I found this way too strong to the point it gives me a headache

Love the smell of these. Make the car smell amazing. You only really smell it for the first week. Then for the next little while you may get a whiff of it here or there. Wish it had a longer lasting scent.

Smells great for the first week or so. If you turn on your heat or air conditioner this stuff gets used like crazy and it will be gone in 2 weeks max.

Although some of their scents can be overpowering, I love the Hawaiian Breeze scent. (I think that's what you call it). As long as you keep the dial on low it could last 30 days but if you smoke in your car it might last a couple weeks if you're lucky. :-)

The clips themselves were a bit flimsy. The smell itself was great, but it didn't last. The first few days were potent and then it just disappeared. Also, the smell only seemed to respond to heat and not a cool fan. Great idea, but I probably wouldn't buy these again.

I use this product in all three of my vehicles!!!! love it!!

great for masking bad odor ....I found cleaning the car works much better

I just got a puppy and this product has helped keep my car smelling fresh and puppy free!!
