I bought a dremel flex attachment probably 30 years ago that didn't last till the water got hot. I also have a rechargeable dremel that is sorta lame. My regular dremel works fine, I guess it's about 20 years old. The little bitty peices doesn't seem to hold up like they used to, guess like most everything they're made cheaper by the day! BUT, you can get into areas with a dremel and cutoff disc that can really make short work of seized fasteners!
