Review on 🔧 Dremel 8220 1-28 12V Cordless Rotary Tool by Robert Pierce

Got this as a Christmas present, I liked it at first. I found it easy to use and definitely has enough power for small hobby projects. Then about a week ago I noticed that the battery was draining very quickly. I would only use 10-15 minutes after leaving it plugged in overnight. Today the charger continued to make mistakes like losing power. I checked the polarity of my 122v dc socket, I plugged my 12v ion charger into the plug and it worked great, then I reseated the Dremel battery and plugged it back in, have a slight arc seen from the charger and it was dead. I probably had a total of 1.5 hours of use on it.
