I like them very much in fact, and received a warmer and some squares for Valentines day, and the warmer is beautiful and a good size. Makes a very nice addition to any room.
I will add one caveat however. It would be nice if the company began to think about offering some sort of tester line, maybe a matchbook of the most popular scents, so that customers can tell what they're buying before they buy it. The scents are extremely strong; read that, EXTREMELY. I melted one square just until there was approximately a millimeter of wax coating the warmer cup, and then had to shut it off because it got too strong.
If you are using it in a very wide open space you may have more time to use more wax, or, as I'm sure might be the case, different scents will be less intense. The scent smells very pretty in the packaging. So maybe a good rule of thumb is if you like it in the package, multiply that by at least 25% for intensity. I'm still really crazy about the whole idea and the company though, so maybe I'll just try another scent.
