Nice unit, with a couple of issues...
The unit I got works well and feels good, especially on my lower back and between the shoulder blades. I like that it has different buttons for all it's different functions. That makes it easier to use than units that assign multiple functions to one button.<br /><br />One issue I have with it though, is that, besides the rather quiet motor noise (that all these types of massagers make), it has an extra "swishing" /"rubbing against something" noise, every time the rollers go under the edge of the "frame" fabric. This is a new and different noise that my other, similar massagers, don't make. I think it's because the rollers actually go underneath the solid piece of  "frame" material instead of staying under the mesh material during the whole rotation. And when they do it makes that noise. It's not that loud so I might be able to get used to it.<br /><br />The other issue that I noticed upon unzipping the unit, when I was trying to figure out what was making that noise, is that the small circuit boards, with the contacts to the top buttons on them, are only taped into place and were dangling half-way off. I just re-taped them but I will have to find a way to secure them better or they will get loose and the buttons won't work. I noticed that some of the low starred reviews were because of buttons not working. So I guess theirs probably got completely untaped. I have made and attached a little info-graphic showing what I found when I unzipped it, and advising putting new tape, gluing or sewing the existing tape onto the fabric, after matching up the circuit board buttons to the backs of the buttons on the fabric.  This should make the buttons work again. So that part is easily fixable, but I'm not sure about that swishing noise.<br /><br />Other than those issues, the unit is very nice. It's comparable to others similar to it. It has no odor or smell to it. The price is lower than most others.
