More mixed results here. I bought an Ozito biscuit joiner some time back; the centre markings and scales on the movable bits are way out, so it's not a precision instrument, but at least once set it doesn't lose the setting so I can make consistent slots without much trouble. Adequate within its fairly severe limitations.
Someone said, though I can't find the post, that cheap tools are OK if all you are relying on is spinning something fast. On that basis, I have a dirt-cheap XU-1 angle grinder that is fine for trimming bolt ends sticking out of fence posts but not good for much else. On the same basis, I recently bought a cheap Ozito cordless screwdriver - with a 2-year replacement guarantee. So far, the battery appears to hold its charge and the thing has plenty of torque. Where it falls down is that the torque adjustment ring doesn't rotate as far as it's meant to, but it rotates far enough to meet all the demands I've placed on it.
As always, horses for courses . . .
