Review (4/5): Great and quick service by seller, powerful and well designed.
Great and quick service by seller. Unit is plenty powerful enough. You have to be careful you could really make you feet sore if you don't follow directions. A fully charged battery lasts long enough for several sessions. I have done four sessions on both feet and is still going strong. Nice not having to try to manage a cord when using it, even though I am sure a corded model would be more powerful. Of course you have to manage charging with this unit and its nickel cadmium battery, so you just have to decide what you want to deal with. Really satisfied with this unit. Only thing that I think might make it better would be a lithium battery. The replacement rollers are a little expensive but seem to be lasting longer than I thought they would. The handle design is very comfortable and easy to hold at different angles. I had a unit that used replaceable AA batteries (different manufacturer) and it was not powerful enough.
