5 of 5 Excellent! January 31, 2023
Reviewer: Pamela P. from Winnipeg, MB Canada  
A friend of mine found your site while searching for this battery replacement. At first my order was on hold and I figured it was because of a credit card error. Nope! It was because the shop wanted to verify which light it was going to before sending it out as it was going into a Fenix light. I thought that was fantastic! It's the little things like this that make a lasting impression when dealing with a new business. Shipped out right away and got to the pickup location quickly. It was -43c with the wind this morning up here in Canada so we will be putting this winter battery to the test. Thanks again!
