Like I said, it depends on the tool. You're rolling the dice. Several of there tools that are actually acceptable and represent pretty good value.
However most of them are unfit for any reasonable use. If you only get one usable tool for every 4-5 you purchase then you have been penny wise and pound foolish.
I think their upper end air tools are decent. Feedback on their cheapy angle grinders is also pretty good.
However I would never touch any of their tools where precision or cutting is a requirement. An example if their cordless drills. You can actually wobble the chuck laterally!!
I bought one of their 1/2 HP 6" bench grinders. What total garbage. The motor is so gutless it stalls out at the slightest load. I measured the running amperage and it was only 2 amps. (another deceptive HP rating)
On the other hand I bought one of their $2.99 digital multimeters. It's perfectly acceptable for basic use. If I need precision I'll dig out my Fluke, but for simple continuity tests or rough voltage measurements it's OK.
