Review (4/5): I like this simple product very much
I like this simple product very much, and I use it everyday since I bought it. it's very efficient. my one complain is the tube. I hope the factory can supply an extra tube in the package. the tube can't handle hot or warm water. the end of the tube broke twice with warm water, and I cut it short. luckily my teeth can handle cold water, most people can not.
