Instead of saying "I love my iQue 110," I'll post why I bought it.
1. The price was hard to beat.
2. I liked the way the unit attaches to the WSM. The "dog dish" stays on the WSM all the time, outside, so all I do is slide the hose on.
3. The fan unit is on the other end of a hose, so I can hang all the electronics under my cook table, where is is in the shade, and protected from an unexpected rain shower.
Some controllers have fan units that attach directly to a bottom vent. That leaves the fan exposed to sun and rain. Plus, I am a klutz, so I can guarantee I would kick that sucker and break it off.
I've had my iQue for a couple of years now, and it has worked well for me.
