UPDATE: After the initial correspondence and information about possible product defects, Pieps issued a voluntary recall on Apr 12, 2021. The recall email is at the end of this post.
You may have heard some controversy about the switch failing on the Pieps DSP Sport Avalanche Transceivers, especially when used incorrectly. There are now many videos showing the issues, such as this one. Pieps is a company owned by Black Diamond. I received a letter from REI (below) and have decided to post it here for anyone who may find it of interest. It includes an important Instagram safety video link (https://www.instagram.com/p/CGT6EzAlgLn/) from Pieps. If you’re using an older Pieps Transceiver, watch this video because it provides important use and inspection information about the devices that every user needs to know.
