Yep, I know what you mean. I have the impact and combi drill and the switch has sort of "stepped" levels instead of a modulation of the speed. Also in the repair channel in the OP, the guy mentions the Erbauers don't have spare parts, so can't be repaired like the Dewalt, Makita, Milwaukee, Bosch and the like. Fingers crossed it lasts me long enoughMy dad has erbauer gear, he likes it, it's ok but you can tell where they cheap out.
The drill and impact drivers for example don't have much control compared to my hikoki the throttle for want of a better word is much more controllable, the speed is greater and units are more powerful, that said my hikoki was probably around £50/60 pound a drill dearer.
I also bought a erbauer mitre saw, the features were fantastic, and externally the build quality was amazing, then I used it, first cut it .smashed the gearbox. Looked at other reviews on Screwfix and there were lots of reviews saying the same thing. Was severely disappointed, ended up with a evolution mitre saw, not as feature rich, and externally didn't look as well built, but I've thrown a lot at it and it's been great and accuracy seems pretty good for a budget saw, probably why they sell so many.
I didn't want to spend too much as I'm not using it that often but also this thing with the different incompatible battery systems puts me off. I do know that Bosch are trying to improve that but there's limited takeup by manufacturers.
Was looking at the Erbauer Mitre Saw, now not so much if it's that bad. I've heard good things about Evolution too (mainly their table saw). They share the same battery system with Erbauer oddly enough.
