Anyone tried these seat coolers before

Saw these and though them to be quite interesting. Would love to have cooled seats.
Just wondering if anyone has tried them yet. Looks like the run about $140 for cooled and $170 for cooled and heated.

I would even take a broken one and just hook it to the under-seat vent.

Looks interesting. Don't need it for my 4 runner but maybe for the beater truck...
