Great looking shelf, super easy to install & most importantly. This as a great purchase! Now I have to ship the damaged item in order to get me money back. There is also a decent level of noise cancelling going on. Están mui bonitos pero! They do not come off your feet when you are walking or going up and down steps (a pet peeve with many backless slippers) because their fit is like a good shoe, and their shape also encourages them to stay on because they conform to the foots shape instead of just being flat. For example, I will hold the handheld and another person wears the lapel and stands in a distance, when we both speak, it will send both input sound sources to the receiver and record into the camcorder. I tried the size I normally wear in keens, 10. I thought that I might have to strap down the back tire but theres not much movement when driving around bumpy/twisty roads. My regular shoe size is 7m.
