I've had the heater installed for about a month and so far it works as advertised. I compared the water bed temp to the heater display and they agree to within a degree F.I really like the unambiguous digital temp display. It's readout is steady if it is at temp and blinks when heating. Nice touch and well worth the up-charge over the dial display. If the bed has been sitting for a while so the heat stratifies in the mattress and then sloshed the display immediately begins to blink, indicating it quickly sensed a change in temp and is re-heating.The digital display eliminates any question what the set and actual temps are. Very nice. Some heaters with dials have no contrast between the numbers and the background and are hard to read and even harder to tell if it is working or failed. The LED digital display solves that.The heat pad is rather stiff and is shipped rolled up. I unrolled and weighted it down for a few hours to flatten it out. That worked good.The heater control comes with mounting screws. i considered putting it on the wall but some claimed the display is too bright or distracting if mounted in view of the bed's occupants. To avoid that but make it readily available I used Velcro to mount it out of view on the side of the bed. So far that works fine.
