Amazon delivered this via Ceva and they were very polite, driver was also nice he wheeled it into our garage. Very satisfied with the machine. Very quiet and smooth operation, couldn't really imagine one being much better for 1000's more. Yes you have to put it together but it was easy. Hardest part was getting it from the garage to the room inside the house. All in all a good buy.

My dentist noticed the difference it whiteness of my teeth. I am a smoker and coffee drinker. Use it consistently and you will receive great results without spending hundreds of dollars on whitening treatments. This wont give you instant results if thats what you are looking for.
