Bests & Worsts Reviews from Amazon

I have a very old Sonicare FlexCare toothbrush, model HX6950, that I bought in 2008. It's not in the best shape these days; I need to open it up once in a while to clean it because a little bit of moisture can get inside due to the old gasket on top. The model I'm reviewing had a good promotion ($10 off the normal price), so I figured this was a great time to replace my old toothbrush. Now I wish I hadn't bothered. This toothbrush vibrates like crazy when in the air, but as soon as the brush head touches my tooth, the vibration almost completely stops. My old toothbrush had a very strong vibration that did not stop once in contact with my teeth. Don't worry, I did follow the instructions to disable the easy-start feature. I actually opened up my new toothbrush last night to see if there was something I could do. The old toothbrush had an adjustable gap between the coil and the magnet that would affect the strength of the vibration. I thought maybe this one was adjusted wrong at the factory. Easy fix, I thought! However, what I found was a completely different design from my old toothbrush. There is no way to adjust it. The vibration is weak by design and there's nothing I can do to fix it. If I had not come from a better toothbrush, I might think this one was amazing. Perhaps that's why it has such great reviews, since it's an entry level Sonicare and most people buying this came from a manual toothbrush. However, since I know how much better they can be, I'm very disappointed. My teeth just don't feel clean after using this like they do with my old toothbrush. I bought this toothbrush thinking the price was low because it doesn't have all the features (cleaning modes) or the big base and accessories like the more expensive models. I could deal with that. However, what I found is that it's cheaper because it doesn't come with all the features, accessories, AND an it has an inferior vibration design.
