This product was bought on behalf of an elderly disabled person who cannot always exercise enough to ensure good circulation in the legs and sometimes has swollen ankles. From the first use the ankles became less swollen and continued use has given a more comfortable feeling in the legs. I have tried it myself and find it very pleasurable and effective. It is not like a TENS in feeling at all, it feels like a pleasant tingle on the soles of the feet then when it goes into muscle stimulation mode it feels like a pleasant vibration that contracts the muscles in a gentle way (the booklet says it is not actually vibration) . It has only been used it at levels between 5 and 10 on the 30 minute default session, the level you select can go up to 99. The level you choose depends on the sensitivity of the soles and the result you are experiencing. The button for ON and the + button to select the level makes setup simple. We did not use the supplied remote. It has a TENS application which can be used at the same time as the circulation boost using the BODY button and supplied pads but we have not used this. If you need to use support hose you will find this a great boon.
