I've been off site for a bit so playing catch up.
Yes, I believe (but not 100%) sure that mine is a Warmrails. As I said, it's a floor model but the plastic feet were very crappy and tippy. Also, as my family could only bring themselves to place (and I mean fling!) towels on top on the top rail and not use the other rails (a trend that continues), the warmer was quite unstable. Hence the move to wall mounting it - and I am so glad for it.
The rails are very warm but not so hot that a casual touch burns a person. On my model at least. A toddler, for example, would find it hot and not touch it again but you'd not have any kind of burn at all. Same for a pet brushing against it for the first time.
As for use, you have to remember that it's a towel warmer and operates at a low heat setting... instant warming is not going to happen. I do find however that on mine that laying a towel over the top rail and having it drape down, somewhat touching a lower rail, warms the towel faster. Also piling a few towels on top of each other in this manner dries/warms the bottom towels faster and then I just flip the pile over when I take off the bottom warmest towel. And when I say "drape" the towel I really mean toss it on there helter skelter and don't worry about it. Folding a towel nicely actually seems to slow the warming process down considerably.
No, the heaped on towels do not scortch (sp?) or catch fire even when left for a few/several days. The lower rails (I think mine has 4 rails total) get used primarily by me... trying to keep DH and DD from using my towel. Or by me using them to dry bathing suits and such.
I do unplug the warmer when we leave on vacation - no sense taking chances and/or wasting the electric money.
As an add.... we mounted the floor model upside down in order to have the electric cord be on the correct side for running it with the extension cord to the outlet. We used L-brackets bought from the hardware store for the mounting.
