Bests & Worsts Reviews from Amazon

This battery checker does not perform as advertised. The problem is that there are supposed to be 18 gradients of battery life, with 1-5 for POOR, 6-10 for FAIR and 11-18 for GOOD. But all these levels appear to be mainly for eyewash, since this tester will show most used batteries to have a full 18 level of GOOD. For anyone wanting a simple "go or no go" tester, perhaps this will do the job. But if you expect true sensitivity to accurately check batteries having various remaining charges, then this item will probably disappoint you. Since it cost $18.99 with shipping, I decided to request return of the tester to the vendor, Battery Superstore. Aside from not being sensitive as advertised, it would not give readings for 2 of 12 battery sizes advertised. After receiving my request, the customer service department at Battery Superstore wrote back stating that although they were sorry I did not like the charger, they would charge me a 10% restocking fee plus the $6.00 shipping charge, and I would pay the return shipping. I wrote once more to question the charges for returning defective merchandise, and they responded that the charger was good, but they would kindly waive the $1.20 restocking fee. Even with this. however, I would still be losing most of my money on the unlucky purchase, so I decided to keep the tester. I will be very careful not to purchase from the Battery Superstore in the future.
