My Dremel 395 failed after about 5 years and I didn’t want a big kit full of accessories since I already had that from the Dremel. The longer you have one of these things around, the more you find yourself reaching for it to do all kinds of things, so I really missed it!
I bought the RTX because of the relatively low cost and its ability to accept the Dremel chuck# 4486. The design appears robust. The on switch at the top is really easy to use. I noticed the 2 Amp motor doesn’t bog down like the Dremels we also have. The only price you pay for the power is that it feels heavier. No overheating problems for us when running on the medium setting. Can’t beat the price either.
