In general it should be OK. Certainly not great, but possibly good enough. Functions worse, it will be fine. The biggest question is safety wise. Looking at the jacks 1)no fuse at all on the 10A range, not good 2)there is no such thing as Cat II 500v. That doesn't exist. unless it's like $10 or less, I would pass.BIL was looking for one, i found this one for a good price at estate sale. Is it any good for a home electrician ?
