Review on 🔧 Dremel 8220 1-28 12V Cordless Rotary Tool by Chris Lacasse

I am very disappointed with this product. It seemed good the first time I used it, but the battery life was only about 15 minutes. Performance decreases with each successive use. I use it for grinding on the 10-20 setting. On my second use, I only used it for about two minutes before it shut itself off with the three battery lights flickering, which should indicate the battery was overheating. However, when I remove the battery, it literally feels cold, in fact the entire device stays cool. Now it gets used up to about 45 seconds (I timed it) before it shuts off. I chose this product based on the reviews but I don't understand how anyone can think this is a great tool when you can only use it for 45 seconds at a time.
