I've had very good experiences with most of the HB stuff.
Problems I have had.
- Adjustable Pittsburg wrench doesn't adjust easily at all, gets stuck and has to be wacked with another wrench to get it off. An old Craftsman worked well in its place.
- Multimeter - they are only a few bucks, but die pretty easily. I have a load of them around though since they are so cheap.
- Small screwdriver sets (like for glasses and really small screws) - these work OK if the screw is kinda lose already, but I've had several sets where the screwdriver itself will deform - better than stripping the screw i guess. Got lots of these since they are cheap but need to buy a nice jewellers set.
Bought a roofing nail air gun when redoing a roof, worked great and saved alot of hammering. In fact I think we have 2 of them now.
Overall, their stuff is good for the price you pay. Check out the generator thread going around, they seem to have worked well also.
