A better heated mattress pad?

We've been trying out this heated mattress pad, and it's been working great. Particularly since our bedroom's outdoor thermometer read a low of -17.1F recently!

We didn't have a heated pad before, so I don't really have a recent comparison. However, this one seemed particular good since it uses DC, not AC (wires are imperceptible; <19v), Queen size) at Ithaca's new Bed Bath & Beyond store. For me, a mattress pad heating from below always made more sense than a blanket heating from above.

Other features we like: When you initially turn it on, this one initially goes into high heat, regardless of the heat number setting, so bed is comfy when crawling in even when set to a low number. Also, has a 10 hour automatic shut-off, and controller makes absolutely no clicking sounds noise I've heard from others. Can apparently can be washed regularly (without changing its shape), but we havn't tried this yet.
