Great tool / additional attachments required

Would Recommend

The tool itself is great. Battery is great. The ADD-ON attachments are great. The attachments you get with the kit are fairly useless. They gave me the EZ-Connect blades yet didn't give me an EZ-Connect bit/mandrel. So those blades (which is what I bought it for) were useless. I had to buy another kit that had the EZ-Connect attachment and about 100 other pieces I'll never use. I thought I was all set for my project but had to run back and drop another $50 on the add-ons.

Dremel 8240

Would Recommend

Works fairly decent, just have to get use to the fact that you have to be patient and take your time while drilling or cutting. Can't try to push it to hard, will cause it to cut off, so have to restart.

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.
