Took it out the package and it doesn’t work. This mouse does the things it needs to do well. Additionally, it is extremely silky and soft. The straps are comfortably stretchy and theyre easy to walk around in. I tried the 3M and Command Strips, but neither would adhere well enough. The cross over top and rushing over the tum hides a large trouble area. My gown is long so I was definitely going for comfort rather than flashy. I wore them around the house to break them in and my feet didn’t get sore at all! I am a bluetooth speaker junkie. These appear to be a knockoff.
