I have a 1/2" regular (like 20-150 ft-lb), a 3/8" regular (something like 5-75 ft-lb) and the 3/8" micro torque (like 20 to 200 in-lb), all of them are the regular Craftsman clicker ones. I got the chance to have them run through a hasty test (i.e. they just ran the test for free, although there's no official paperwork or NIST traceability) on both of the 3/8" ones when the calibration lab was in one day doing the company tools. The micro torque wrench was accurate to 3% CW and 4% CCW mid range and the regular 3/8" was 4% CW and 6% CCW mid range (most torque wrenches have some variation at each end of their range). I can live with that for 1/3 the price of Snap-On.
I keep them in their plastic trays and unwind them when they're in the tool chest. There is a lot of plastic in the tools, but I think for non-professional use, if you are careful there's nothing wrong with them. Neither of the ones I had checked were grossly off at least. So other than the lighter than Snap-On construction, can't complain. Had the micro torque wrench now better than 10 years, the other two at least 6 years now. At the time I didn't have much money and figured that having the 3 major ones covered for the price of just one Snap-On was better than nothing. I assumed that at some point I would replace them with Snap-On as they wore out or broke, just hasn't happened so far.
