Compex Wireless USA 2.0 Review: Output and Programs
Four pods work two muscles on both sides at once, across strength, warm-up and recovery programs plus one TENS program.
Testers used the warm-up program to wake up the back and core after a day of sitting, in sessions of about 20 minutes, and the relaxation program after heavy leg days.
Bottom line: a full sport program set.
Control and Wires
Owners like having no cables to manage at the gym, and the remote prompts make starting a session simple.
Testers wanted clearer guidance for the strength protocols and note that each program works one muscle group at a time.
Bottom line: easy to start, slow for a full routine.
Battery and Pads
Testers got more than ten hours from a charge, so short trips need no charger.
Some owners say electrodes lose grip in long sessions and that pods can jam on the charging dock; clean skin helps the pads last.
Bottom line: long battery, pads are a running cost.
Warranty and Clearance
The maker gives two years, three with registration, and the unit is FDA-cleared.
Read the safety section of the manual before the first session: keep pads off the chest area.
Bottom line: two years of cover and FDA clearance.
