Got unit back very quickly with checklist enclosed. It was shipped securely, which was good, as the box took a hit in transit. Self test works. I am impressed with the response.

Very pleased with the cost of battery replacement service for my ACR PLB. Turnaround was reasonable and quick. Communication was great as they kept me informed as to receiving my PLB, when replacement was complete, and when it was shipped back. A bargain at half the expense of a new one. I highly recommend them.

This was a smooth and quick process. I had a PLB that was given to me, and the battery was out of date. The battery was replaced and the unit was tested and returned.
