I also have the Walmart torque wrench. It may not have quite the precision of a high dollar wrench, but it is good enough for everything I use it for. Someone mentioned rebuilding engines, where precise torque numbers are critical. That requires a high quality wrench. But wheel lug nuts, hitch bolts, and most other things I would do are expressed in a range of torque values. In all those situations I feel being somewhere within the range is good enough. If you're over a couple of lb-ft, nothing is hurt. My torque wrench easily fills that bill. If I were tearing down engines as in my youth I'd have a much better wrench. For what I use it for now, the Walmart wrench works very nicely. As always, just my opinion and not necessarily agreed to by others. Nothing wrong with a high quality wrench, though, especially if it makes you feel better.
