Very Good - does what it should

The Panasonic EW6021 TENS therapy Nervstimulator is set easy to use and yet sufficiently flexible. The included adhesive pads you have to clean it under warm, running water, so that they acquire their adhesive power after about 5 applications. This works fine. Allegedly they consider 400 applications, I do not think, but let's see. The adjusted current strengths and pulse types are generously sized; if you really need twenty continuously adjustable intensity levels to be seen. The cables are somewhat delicate and could be good longer by 20-30 cm. The automatic winding system is very well thought out. The individual applications are limited to 15 minutes in duration, but one can start again or set the pulse type manually.
The unit is supplied with 4 pads and batteries, so just unpack, insert batteries, plug it pads, read carefully manual (electrode must not be mounted on the left side of the chest due to the risk for the heart) and you can get started with treatments. In summary, I would buy the device at any time.
