i've had mine for one year, and the only bad thing that's happened to them (i have 2, actually) is the back buttons on both have accidentally cracked thanks to my 1st grade cousin stomping on them unnecessarily.
so as long as you don't let your litlle relatives abuse it, it will last a long time.
my pads still work, the pads are just cracked, but it doesn't bother me.
you can play in socks or shoes, but if you play barefoot there is a small chance you'll hurt your foot on a screw or a corner of the pad.
i give them a 9.5 out of 10.
