You probably have much better metrics than anec-data reports about app use, but I'm very happy WPSN supports Roku. Other than amazon prime, the only other streaming I've been watching is a dozen or so gun channels on Youtube. Delighted to see some of those same channels here.

Does Trex Arms know about WPSN?

thanks James!
Yes they do

Agreed, I watch almost exclusively on my Roku. Unlike many Roku channels, the WPSN channel actually works consistently and does not take forever to load.
