I am now since about 3 months in the possession of this little helpers and have to say that I'm surprised more positive than initially expected! The Saneo Sport EMS device is easy to use and has no superfluous features / frills! The supplied electrodes keep amazingly well, despite repeated use. The supplied electrical cables that have to be connected to the electrodes and the EMS device a good length (not too short) so you have a very good range! From today's perspective / training level I can also say that the device has proper power because twitch training during the toning and dance the muscles just so, a correct muscles as real sports I have so far not yet had. To solve tensions, especially in the shoulder, neck area is worth the portion of gold!
As a single disadvantage, if you can call it a disadvantage because I find it a little annoying that you can connect only four electrodes, so it takes a bit longer if you want to edit multiple muscles.
Otherwise, I can recommend the device only warmest!
