Wonderful tool

I did not know anything like this was around. Always relied on self developed tests for checking batteries including using a voltmeter.

The great thing about this device is the algorithm determines the milli ohms that is internal to the battery. Thus providing a rating of the battery condition. Great preventive test before take a long road trip.

Before buying, I inquired about the product with the seller. He answered my questions quickly and correctly. The product arrived within the agreed delivery time. In original, unopened packaging. Thanks to the seller!
Unfortunately, the tester is faulty. I reported this to the seller. I confirmed all this with pictures.
The seller was very helpful. He said he would pay the price back. He has since done so. Correct, helpful seller! High praise for him. That's rare. With a calm heart, I can confidently recommend the seller to everyone.
