I used to give this product a good rating since it did the job well. It was then discontinued, so my husband and I have become "users," meaning we tried them out for about 1 month. Now they are all gone or really expensive, and we've found nothing that's as effective. My husband has tried other brands in his quest to find something even remotely comparable that actually works but none of theirs do. They're expensive too.
Bad review

The device works but after two months of use it broke and I ended up spending $30.10 for a new one from somewhere else. Not too satisfied since the first one didn't last that long. The only problem is I have to buy another.
Bad review

I purchased this product because my husband has dry mouth and is always looking for something to help him with it. He had the original oral b sonic toothbrush since they were first introduced. It lasted 10 years until we finally tried out a more modern electric dental brush. This newer version was too weak for him, he can't get enough vibration that makes his teeth feel clean, so back it went.
