My fiance bought this for me a while back, and until recently i haven't had a chance to actually use it. When i turn it on, it will start up but when i apply it to any surface it shuts off. I basically assumed it just needed to be charged, but when i go to charge the battery, no lights turn on and no charge. I would return it but because it was a gift, I have no receipt. I like the idea of this product but it seems as if i got a bad battery or charger. This thing is essentially brand new. I am not very satisfied with the product at all.

My initial impressions of this Dremel, after purchasing it at a big box store, was good [not great]. I liked how easy it was to change out the bits, and it did a great job grinding off some nails that I needed cut down. Recently, after sparingly using it, I tried out the buffing bits to bring some brass knobs back to life. Junk. Period. It lasted maybe ten minutes and petered out. I initially thought it was the battery so I let it recharge overnight. Next day, same issues. Starts up and as soon as I start buffing or crank up the speed it dies. In total this Dremel lasted a total run time of under thirty minutes. This is the last time I will purchase a product by Dremel, and I will highly recommend individuals against purchasing their products. At the price point they sell these rotary tools at you would expect a high level of quality. Worst tool I've purchased to date.

I received the 8100 as a gift about a year ago and have not used it until about a week ago. Since then overtime I trie and turn it on I have to fiddle with the slider switch to get it to work. Some time taking multiple tries before it will turn on. So disappointed, if I had a receipt for this I would take it back.

I bought this a month or so ago and used it for the first time today (5/15/16). It does NOT perform at all under the slightest pressure when I used a small cutting / grinding wheel. I have to constantly turn it completely off repeatedly then back on and it shuts off again with such little pressure it's almost useless. I'm assuming I have a lemon / bad unit as the other Dremel products I have purchased over the years have been fine. Glad I sent in the warranty (a first for me) I will wait to complete my review after I hear back from Dremel as to how they handle this situation.

Worked well for about 30 mintues. It now will only turn on for 2 seconds before shutting off. Have charged and tried many times over the last couple weeks--no improvement.
