I bought it on Amazon (link to item https://www.amazon.com/MelodySusie-Professional-Rechargeable-Portable-Scamander/dp/B07P7Z1JF1).

Thank you for the tips! I think the e file I have will work. It has 30000 rpm and I can use the same tips that works for the dremel. https://www.amazon.com/dp/B07P7Z1JF1/ref=cm_sw_r_cp_api_glt_i_BR3GPVQHY2B6VCMHZRF2

I tried it out yesterday and it eats through the foam pretty quick.

I had that same $20 efile to start out and it was so terrible, even though I didn’t realize it until I switched. Mine eventually stopped working off and on like you’re describing too and I finally just bit the bullet and got this one from Amazon:

SO. WORTH. IT. It works so much better! Way easier to control. I think there was a coupon and I got it for around $70. Wish I would have just gone for this one initially and not even wasted my $20 for the cheap one.
