I ordered one, too. Didn't get it yet. I think the idea of using a thin wire with thin insulation is not the best. The insulation has to be thin to allow transfer of heat but then again this would also mean heat-loss to the environment and drain on the battery. An insulating strap is a better approach. Of course, this means that focusing is not possible. The best approach would be to focus, activate the focus clamp (thanks for inluding that, Pentax) and attach the dew heater.

I got mine. Itís a little wider than I thought it would be. I havenít used it in photography yet just a few tests. It is possible to move forward enough to focus as far as I can tell.

Good for you.

I have a similar one, I think a bit narrower strap than yours, and used only once so far to prevent early morning dew last winter. It did what it was supposed to, and plenty cheap enough at less than $20. With photography I usually think I have to pay triple what something is probably worth for it work.

Note I have to talk myself into being up early or late and in the cold. Lol.

I think that's kind of the idea behind this. Once focus is locked, and the clamp put in place, the focus shouldn't have to move as the stars won'T change their distance Then you can shoot away all night with the dew heater in place.
