The device is easy to handle, opens up after extensive reading the instruction manual. I put it like "the way" when I write something on the PC, for example. Important: The skin must be dry and, if possible, of course, free of grease, so that the pads stick optimally.
Handling is relatively simple, you can make the glue to reach places alone. Initially, the cool pads are used to. Through the various programs -There are a surprising number of different areas of the body for 6 and with four different "treatments" -, the unit is very diverse. I've been using it for three pain regions.
Use the back / neck area and the cross: In the upper part of the shoulders I find the pads too small, here you have to either exactly a defined point of pain hit or run a program at different parts in succession, otherwise it will not bring much. To relax in between, for example, after a long work on the PC or in the garden, the unit is also very good to use.
Under cross-easy to install and also good effect.
Use the knee: Super! Very effective, beneficial. The pain, otherwise always there, was away for days after just one treatment. Phenomenal.
15 minutes running a program that ranges from the beginning. Too long use may lead to an intensification of pain in my experience. Sticking to the pads should also not among those running on sites nerves, which is unpleasant.
Conclusion: A great part of the prevention of pain after one-sided work, for small batches to relieve pain and release tension very well suited also as a complement to other practices such as gymnastics, etc. I also think that it is so small and take anywhere.
