Mini massage gun or full-size — which should I buy?

If you travel, work out at multiple locations, or mostly target arms/calves/neck, a mini (like the Bob and Brad Q2 Pro) is far more practical. For home-only use on bigger muscle groups, the longer handle and higher stall force of a full-size gun (Mebak 3, RENPHO Thermacool 2) is easier on your wrist over long sessions.
