Depends on where you're using it
Size: 16 Fl Oz (Pack of 1), Style: Pawsitively Fresh
It's great that veterinarians approve this product as one of the safer options for pets. It smells good and it does the job as good or better than others I've tried. The reason I won't continue to use it is that it is a heavy liquid and when you spray it into the air, falls to your floor very quickly. On tile, it leaves a shiny oily "wet" patch that can make the tile slippery which is dangerous and on carpet, since it is oily, I assume that dirt will quickly adhere to those areas forcing a carpet cleaning in a short amount of time. I happen to have cream carpet.

Nice
Size: 16 Fl Oz (Pack of 1), Style: Pawsitively Fresh
It's fine. It works well to mask the scent of whatever you're trying to hide. No residue. I just wish it was a bit more citrus-y.

It works!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
There is a strong smell or roasted coffee beans but since I started using this product my edges are healthier and the hair at the middle of my head that has been struggling to grow is gaining some length. The product itself can get hard depending on the temperature of your room but if you use it as directed the texture isnt so bad. The oil is thick and not very greasy or difficult to wash away. Definitely effective. 100% will recommend.
