H-WAVE EWLP-4 Machine Electronic Neuromuscular Device Machine cosmetically in great condition has alot of new pads and original carrying case but i believe it will need a new battery installed when i disconnect it from power outlet it maybe last a minute and loses charge this machine is older so thats what im assuming has original power supply selling as is. Priced significantly lower than all machines in order for you to get a new battery installed after the new battery will last you years
