These are basically the disposable model, I've been through so many of these. Philips does a good job of warranty exchanges, but the ones you receive under warranty have no serial or model number, so then when your replacement dies, you have to backtrack of which one did it replace and if that one is still under warranty, got tired of all the messing around switched to Quip. Will start replacing the other 3 sonicare's in my household as they all die.
This receipt will be available on amazon, but if you ever buy at a B&M store, email the paper receipt to yourself or something. I have uploaded receipts to my profile and had them disappear when warranty time came up.

One suggestion… when finished brushing teeth, pull the head off so it just sits on top of the handle. If not the seal will get nasty and fall apart.

In comparison chart, this 4100 model has pressure sensor and 2 intensity settings.

Buy the 1100 model for $19.95 instead. It does the exact same thing. It's the best one I have ever owned.

I like the pressure sensor and the head replacement alert. For only $5 more on sale the 4100 is worth it to me.

Any difference between this and manual toothbrush ?
For people with gum issues the electric is better. Plus people tend to overbrush with manuals which can be rough on your gums as well. I feel the electrics do a better job of cleaning your teeth.

Might as well go for the 2100 model for only $1 more. I do like the pressure sensor on the 4100 though.

Unfortunately, yes it does. It will last a couple of years though. But then the shaft definitely break internally at some point. At that point there is nothing to do but throw it. I had it happen too many times. But then it happens in more expensive sonicare brushes too. I used to have a $120 so I are brush and the same thing happened. Learnt my lesson. I still like Sonicare. But don't like to spend more than $30-$40. Also, usage wise, there was no difference I could discern between that expensive model and this one.

Actually, this model does not have the shaft issue, it uses a lower-end motor

One thing to note about the sonicare. They changed the product at some point. It used to come with a two prong power plug charger and the unit was thicker. It had a slightly more powerful motor as well. They changed it silently to provide a USB plug instead so you have to use your own charger. And the new model is appreciably thinner. But if you use it at the higher setting (have to press the button twice in this unit), the difference in power is not that noticeable.

Luckily the old charger still works with this one, even though the size of the brush is less thick now.

This model uses a lower-cost motor, however it does not have the shaft issue that you experienced on the higher end model.
