I have the Ozito red battery powered tools, rattle gun is great, hammer drill is also good, tek gun I thrash, the only problem I have had is with the angle grinders I have 2, 1 I use with the grinding disk and the 2nd with a flappy disk, they cop a thrashing every weekend, I have changed the grinders 4 times now, and the warranty starts again each time you change them, the last time they didnt have any so they gave me my money back which was the current price, not what I paid for the first one 6 years ago, 6 years use and made a profit
I tried one of their jigsaws, I could have bashed a straighter line using a hammer, I took it back and they refunded me, so I would say for precision, you need to pay the extra.
