I too have extensively used the cheap H.F needle scaler as well as about 3 sets of replacement needles to date and it has held up pretty well, for a cheap tool made in who knows where. They work well on flakey paint and rust but like RedBeard said, it's best to get the heavy off with the needle scaler then procede to blast the remaining paint and rust. If you have heavily rusted metal where it actually starts looking like layers of cardboard peeling apart, an air chisel with a blunt tipped chisel works great to knock the "delaminating looking" sheets of scale off in big chunks, then follow up with the needle scaler, then mediablast. The air chisel hits with way more force and it literally vibrates the scale off in sheets, just don't use it on anything thin enough to get dented or punctured.
