Dremel battery is junk!!

Would Not Recommend

I have the Dremel 8220 and although a few years old it has only been used a couple of times. I pulled it out this week to use it a d it won't run. Charger works but battery apparently doesnt charge b/c tool is dead. Seems like a common problem with this brand/battery. For the cost of this tool, Dremel do better! So disappointed in this product 😞

Woo Hoo no cord

Would Recommend

Seems to have the power of my corded tool without the hassle of cord. Wish it was a little smaller for easier use. Have to see how long the charge lasts. So far still running off the first charge.
