I had their compression tester from about 6 years ago, which I use in my shop now. Whenever somethings a little off, I get the snap on one out and re test, but the HF is always dead accurate. I also use their orange body panel tools, they look like little 6" swords, for taking off wheel weights and they've held up over a year and a half. My $70 "Storm" digital micrometer I bought through Mac had a sticker over the Central Electric logo embossed on the box, which retails for 8.99 at HF. Their hub puller/slide hammer is a POS, and the air inflater/gauge didn't hold up very long.
