Mostly I had other expectations, I thought it was like a heating pad, just as hot water bottle, ie, when used constantly in the socket, but the hot water bottle is almost like being on a charging station loaded (ie my fault that "up to 6 hours heat "should have made me stuzzig ;-) But this has not led to points deduction). It takes, however, more than 10 minutes, at least one quarter of an hour. Then it is very hot, so I have to raise the coating (as snaps or Velcro would have been practical, it is open). I have not yet looked at the clock, but .... 6 hours maybe, but clearly, it is only lukewarm. But you can not in between again 'charge', so long as it still has a certain heat, which I find very impractical.
It is really very difficult (it's also something thick it clear that technology for warming, but does that not also thin ..?) Could be for larger.
The connector would be better on the side instead of in the middle of such an area, so you have to be careful on what surface you lie if necessary (and I shoot hot water bottles already at times, because the warm water is indeed down and thus this page is warmer )
The advantage is clear, it is much more convenient, they sometimes just at a station 'dock', as warm water. That's why I keep it well, for 15, - is it, a lot more money but would not pay for it.
Correction, seen shortly after my review: The reference can be tightened with a belt. I like not so, but it is better than openly
I can add still, that the cable is badly short (just under 1m), I probably beside the couch into a power strip, but that the heating pad in sight is right (to see when the light goes out, so it's charged) is a bit scarce (let alone, you want the "charging station" / the cable does not have so visible, but hiding something behind the back).
Meanwhile (after almost three weeks of use) wear out even the plastic closure on the pillow, he no longer holds as well.
Update 16:02:13: The lock is now completely gone off, the edges fray (because I do not use the terms?), And yet I do not want to miss it, it is easy to practice, they sometimes just plug it in and just this time of year for 'Frier bag' like me.
Update March 2013: It has a loose connection, you have the cushion during heating stick, so that it heats up further. I'll complain about it
