## Customer Reviews

### ⭐⭐⭐⭐⭐ This tool is a MUST have for any serious batteries DIYers
*by F***T on July 13, 2019*

It's rugged, simple and just works reliably. i don't know if it's accurate nor do I really care since it establishes a reference baseline for comparing one good cell against another. The measurement is much more stable than another brand I returned - which also worked. I only wished it could touch hold the value of interest - the higher for voltage and the lower for resistance measurement. Although it's reasonably priced against others I wished it was 40$ includong shipping, which is the lowest I found on Ebay. However... After a month!...I received 3 LEGO's sample pieces! I got refunded by Ebay of course but never got apologies from the vendor. So I used Amazon instead at 70$ 2 days Prime.

### ⭐⭐⭐ Test leads are too short.
*by B***1 on April 12, 2022*

Test leads are way too short.

### ⭐⭐⭐⭐⭐ Great for figuring out which battery us bad in a pack
*by A***R on November 14, 2021*

I had a UPS pack that said it was bad. But the batteries were only about 3 years old. All held a charge, but one had very high internal resistance. Swapped it out.... perfect.Used it to find a few bad cells in a pile of rechargeable batteries.
