I got myself a cheap Fascial Gun (model Manyeli SK 668) – there are a few terms that are being used to describe the same device (fascia gun, percussion massager, massage gun, muscle gun, fascia gun massager, deep tissue massager), but basically it’s a massage device to help with muscle recovery.

I purchased this Fascial Gun for approx $40 and it’s almost 1/10 the cost of a Theragun Prime $499 so it was pretty cheap. I haven’t compared between the two but I’m assuming they both do similar functions. Maybe the Theragun Prime has more features and will last longer but can’t see why the $40 unit doesn’t do the job.

I have been using it for about 3-4 weeks and it seems to do the job. I mainly use the fascial gun after my runs (when I am sitting down at my desk) to massage my calf muscles and thighs. I also use to massage my wife’s back. She isn’t a big fan of this device and mentioned that she feels itchy after using it.
