I never had one until last month. Because of covid19 we didn’t have Christmas with family last year and on the 4th of July we had a party at my nephews and I brought him is Christmas gift and he had mine also. And I got a harbor freight oscillating saw. It is still in the box as I haven’t needed it yet. I might just have to find something to test it on.I never knew how much I'd use one till I got one.
