theyre SO cute, BUT! My bf liked the foam. Con respecto a la señal: Va bien y es inmediata, pero lleva mal la cercanía con emisores eléctricos (centarlitas de alarma o acceso, etc. I was a bit concerned with buying this one, given some of the negative reviews, but I ended up giving it a shot anyway. Otherwise you would be toggling the active devices while trying to answer calls or listen to audio. This will damage horizontal bar where it rest. Measured up, used a level to get it perfectly horizontal, marked the two anchor locations with a hole punch, drilled out the two wall anchors, tapped them in and then drilled in the two screws. My issue was that one of the extendable arms had a fair amount of rust. Not as good as the frame mounted type of kickstand, but it works well for a kids bike that had no kickstand. I was so impressed I ran to the wife and had her put these on and do the whole "3D barbershop youtube video" thing and she was impressed and got mad I didnt order her a pair.
