Very hit n miss anymore. I bought a grinder one time swore it was junk after awhile, posted here about it and someone suggested I replace the grease in the gear box (what grease) did that fixed the issue, its not the greatest but its good to have to switch between when the other 2 get hot. Got one of those portable band saws, for the $59 I paid its been working great and that so called wood-only bandsaw blade is bullshit, I'm still cutting CRS, HRS, and other hardened steels with the original wood only blade, cut up a bunch of hardened milling vise jaws and it sliced thru those like butter.
I went there to buy one of those large angle grinders but the display showed a model with a rotating handle the ones in the boxes were something different, I didnt buy. Will save my $ for a name brand that is lighter and has vibration reduction built in.
I could on -n- on about good vs bad, I think the first post nailed the disposable vs worthy to try it out.
