I am SO PLEASED with this product. I started using interdental brushes a few months ago, after a couple “bad” checkups despite regular brushing and daily flossing. The hygienist suggested trying interdental brushes and provided a sample brush (NOT Pikster). I found it very difficult to use; I also found that the wire became weak and bent after only a few uses. I checked into some other brands and eventually discovered Piksters. Any interdental brush wire is going to wear out; that is just the nature of the design, but I have found Piksters to be the best. I can usually use a Pikster brush for a good one to two weeks before the wire fails.Because I was so pleased with the brushes, I decided to give the Power Pikster a try. I like it very much and definitely recommend it. Be aware that there is a learning curve. For the first week or two, I had to allow extra time in the morning as I learned to use this tool, but now it is a quick and easy part of my morning routine. The vibration definitely makes the brush more effective and easier to insert between teeth (at least in my experience). It is easy to put the brushes into the handle and it is easy to recharge the Power Pikster, using the USB cable supplied. I use it with the Piksters’ Kinks brushes for my back teeth and their straight brushes for the front.I must acknowledge that there is a problem using the smallest brushes (size 1 and below) with the Power Pikster. The small brushes are easy to insert, but unfortunately they also easily pull out of the handle. Again, this ONLY happens with the very small brushes, so will only affect those who, like me, have some very tight spaces between teeth. I contacted the Piksters company to ask about this, and received a quick, friendly, and helpful response. They are aware of the problem and are working on an adaptor to use with the small brushes. I do not know whether the adaptor will be offered on Amazon, but it may be, if enough people express interest. They were kind enough to send me two adaptors to try, and both work BEAUTIFULLY. I have not had a single brush pull out of the handle when using an adaptor.Even with the issue with the smallest brush sizes (which the company is already addressing), I heartily recommend both the Power Pikster and Pikster interdental brushes.
