These are the most well-built boundary mics I have ever seen, and I expect mine to last many years. The item does stay in place, does not ride up like others I have had in the past. and so did I. They are really small to carry around so very easy to misplace but this is up to you and your ability to keep them tidy! I bought a pair in 2010, they just broke. Very good quality and will definitely buy again if I need to. It is pretty loud as well, matter of fact I had to keep it at 65%-75% volume because I didn’t want the neighbors to complain. Stable, wont budge once installed. Like a few others said, for a sketcher they are not nearly as padded in the sole area, but generally I do not do a lot of walking around in winter in slippers. Their products will do the job but you might have to put a little more effort into the assembly process.
