One of these was recently installed by my landlord. The design is pretty terrible. It has numbers on the surface, but they are so far away from anything that moves when you set the temperature that you can't actually see what temperature you've set it to. It also doesn't keep whatever temperature very well; at least in my installation, if I set it to a comfortable temperature, it will wait too start heating until I'm uncomfortably cold, and stop heating when I'm uncomfortably hot. People have told me I'm not particularly sensitive to temperature, so I'm pretty sure it isn't just me.
