Customer Reviews

5 star rating  Efficient Process
Jim from US, Arkansas, Springdale
Product selection and receipt of order was refreshingly easy and efficient. Unable to rate product quality at this time as I ordered batteries that are not yet needed. Hopefully, quality will be as good as the process was easy.

Arrived as ordered, unlike batteries from other suppliers, these all worked out of the box.

Replaced the old battery and got several days more of light in the flashlight used every day for an hour while jogging. I'm impressed.
