I asked this question a little while ago, didn't end up buying them, but I did buy some other OTC tools, and I will NEVER purchase anything OTC again.
Bought there battery kit - cam with some disconnect pliers, terminal cleaners, and a couple of other things - don't remember how much it cost, but man - SERIOUSLY CHEAP. The pliers were put together, then chromed so there was a black mark where the two pieces of steel overlapped. The metal felt very cheap and the rest of the set was garbage as well.
I have heard good things about some of their tools, but unfortunately I'll never trust them again.'
Someone wise chimed in when I asked the question that it is best to go with something that is easily replaced (warrantied) whomever that may be in your area, as these tools can be some of the most frequently damaged.
good luck.
