Just got this item, and used it on 2 trips so far.
I was debating between this and the hotronics snapdry, which are similar in concept. The pivoting nature of the arms is why I picked this one.
It will put out slow stream of air that are just a little over body temp, so no worrying about overcooking your boots, and my not-too-wet ski-boots were dry using the 3hours timer.
One thing to note, the unit has a "fragrance" bar in there; which adds fragrance to "deodorize" your boots. The smell is not good, a little like weird housecleaner, and will prevade your room. The instructions do say that over time it will wear off, hopefully this occur sooner.
If it keeps working as it does right now, I'm happy with it.
But giving it 4stars, because although it's the premium model and expensive it's missing some things that other products have:
-nozzle tips for glove
-disassembly/fit into your boots capability
-12v adapter to use in car.
