I once bought a HF planetary drive torque multiplier for wheel lug nuts just to keep under the back seat of my pickup for roadside emergencies. It's good thing I decided to try it out when I got home. The 1/2" drive snapped off at the socket on the very first lug nut! It looked like the drive was made of cast metal. - Colossal fail!
I brought it back to the store and they offered an exchange, but I took a refund. I didn't want to make another trip to return a second one. On the other hand, some of my other HF purchases are passes.
#34552 small tire changer is a pass. I have used it to change tires on my kubota bx tractor and on my classic mini cooper (it has 10" wheels).
The static wheel balancer does a passable job (after fine tuning it).
I have used the #67224 6pc. rotary saw blade set to cut screw slots in CRS and the blade used is still sharp, so they get a pass.
The snap gauges are ok (they need a little massaging).
The HF transfer punches also pass except for the cheap plastic storage holder, but I have only used them on aluminum so far.
HF acid brushes and chip brushes are the best bang for the buck.
I bought the #94447 6pc. "technical" measuring set just for the inside and outside calipers and they are ok, but the scales and the slide caliper are junk.
The HSS drill bits haven't unwound on me yet and they are reasonably sharp.
HSS tool blanks pass (What can you say bad about a single piece of steel).
At only $20, I am actually quite pleased with the P37772 digital multimeter.
I have bought other small tools and items, but never any power tools.
I share the opinion that if an item has no motor or not too many moving parts, you might find a good deal at Harbor Freight.

If you don't have high expectations, you won't be too disappointed.
