Review on 🔧 ES4 340CN Certificate Calibration by Summit Tools by Boss Spangler

. The Rave Online is a Ditch Flick and Go Digital that I'm not a fan of, but this torque wrench changed my mind. The main draw for me were the AA batteries (no stupid fancy batteries) and a nice big digital display. What I didn't expect was the great hard case and the fact that I can use a simple coin like a quarter to push out the battery compartment. The reading is silly just to look at and big enough that I could see the numbers no matter what position I held it. It should also be noted that reading is very fast. With each additional push, I could see the ft/# go up 0.1 increments. I only rated it a 4/5 for accuracy instead of a 5 as I have a torque tester to see how accurate it is. I expect to change that score to 5 at the end. I could ONLY be happier if it was cheaper, which can't be due to the quality. It contained a personal sheet as tested at the factory. After all, this purchase is a no-brainer - just do it and you'll be happy with the results.
