IceProbe Chillers - Do they work?

[Centerline]

I have this little 20 that is starting to heat up a tad. Anyone use an IceProbe or ANYTHING other than an actual chiller that worked to bring the tank water down 3-4 degrees? Really, really don't want to see a chiller sitting by this little 20.

Yes, I used an ice probe on my 20g qt this summer. Temps in the garage up to 90 degrees and ice probe kept the tank in the 81-82 range. Definitely a useful piece of equipment for me.
