Definitely a solid device with exceptionally low price
I've been using this device to pop my invisalign trays in the morning and at nights for the past month to clean. It's been doing an excellent job and I've been using the Retainer Brite tablets without any issues. You have the base that vibrates, then the container that is removable from the base and the lid. Best part is you can use batteries to operate or can always plug into an outlet - both work great! It does make some noise, so it's not totally silent, but other than that everything else is A+. Sure it's not the most stylish looking device on the market, but for the price, size and cordless experience, you won't find anything better.
