Would it have killed you to describe what the various settings do?!(M1, M2 & M3). I can’t discern any difference between them. Also, your help website is dead. If it weren’t so (purposely?) difficult to do I’d return it.
I use it almost every evening.. if your feet are cold the heat setting will NOT warm them up however there are three functions and they are wonderful. Personally, I like 2 and 3 the best.
[This review was collected as part of a promotion.] Bought 3 of these as Christmas gifts for sports enthusiasts in my family for Christmas. All seem very happy with them.
After a long day of work, its nice to come home and use this product. I have had foot massagers in the past that had more massage strength, but this one gets the job done too.
