The circumference of the terminals was too large for no shims and too small for the post and the shams. The diameter is too small and the negative clamp is too large.

I had received a used product from them by mistake and they wasted no time replacing it. They even offered a refund without send the used model back. This company will care about how you feel. Plus the product is worth the money, accurate, and looks fresh.

These things are sweet. Screen looks better in person than pictures. Fit my battery posts great, voltmeter is a lot more accurate than I anticipated, definitely usable. Unless you’re super finicky about tiny nicks and scratches there’s really no immediately apparent faults here. Haven’t tested power draw but I can’t imagine it’ll be an issue.

Will be buying more for my other batteries.

1.0 out of 5 stars Not worth your time
Reviewed in the United States on December 23, 2019
Got this thinking it’s cheap enough but will look good and be easy enough to install. They were too big for negative and positive and with the sleeves they were too small. Couldn’t even fit around them without serious hassle and bending and stretching it if you really wanted to get it on there. Negative broke with little prying to fit over the sleeve so I was forced to use the positive one on the negative side. Fit fine with the positive terminal and the sleeve on the negative side but that’s natural seeing as positive is always slightly larger than negative. All in all not worth even the “lowish” Price it is for the set. Just a hassle for no reason. Btw I never leave reviews but this one made me want to leave a review and so now I’m forcing myself to actually leave reviews to my previous items.
