Had a problem with the battery in one of my new RT Mountain radios. The team there diagnosed the problem, quickly and correctly and sent a replacement free of charge. Everything is working great now. Thanks.

Rocky Talkie has exceptional customer service. I have been using Rocky Talkie since 2019 on adventures. My new batteries were delivered as promised and I needed the radios around the house & yard after a family member's surgery. I mentioned the great customer service to my climbing partners who also have the radios and some of the members on my volunteer SAR team.

One of our radios had a bad battery that crapped out after only a few charging cycles. Rocky Talkie support quickly shipped a free replacement battery with no hassle at all. It's a relief to get great customer support these days. Thanks Rocky Talkie!
