Harbor freight has their Quinn equivalent for $40 with coupon. It tested really well.

ACDelco Store based in California is one of the worst companies I have dealt with on Amazon. They sent me a used digital torque wrench and when I messaged them about it, they wouldn't reply for 2 weeks. When I opened a case with PayPal, they finally responded. After I sent it back they wouldn't refund me for 2 weeks after receiving the return. So to summarize, they don't do anything until you press them to move forward.

I feel like a more permanent price drop is warranted for these name-brand meters given how good the reviews for the cheap no-name $30 units have proven to be. Also some of those newer cheap meters have more cool features.

They're all made in Taiwan anyway, you might as well get the HF version for cheaper and with a lifetime warranty.

May I ask how you made an Amazon payment with PayPal?

There are tons of these on Temu for between $20-$40, that look exactly the same.

Slapping an ACDelco label on a cheap product doesn't magically make it now worth $55.

Have been using a no-name brand purchased from Amazon a year ago and its working out pretty well. I tested it against a digital craftsman unit and the calibration seemed off by a couple of N-M. I now factor that variance in my usage. The Quinn brand at Harbor Fright is also decent. I know someone who has been using it for a while and swears by it.

Also remember, the size of these Torque Adpaters may not allow them to be used in tight spaces.
