Excellent product! Fast 4 days shipping from Poland by Itella. Device really works and quickly relieves muscle pain. I guess that tendons and joints need longer time for pain relief. Using hydrocortisone or heparin gel will speed up healing effect in all cases.
There was confusion with included power cord. It doesn't have grounding and I advise to replace it for your safety.
Also I'm going to buy newer model to evaluate the benefits of it. Recommend seller and product.

The equipment arrived in perfect condition very easy to use

Super device. It works like a professional. Very fast delivery. I recommend this device and this supplier to everyone.
