Hi, there...
Yep, it's a handy cooler, but with their accessory additions (120v plug adapter instead of USB/battery use and tubing accessory). It's not really useful without the tube adapter they sell.
I have also placed a custom timed filter refill to ensure the spongy filter is always wet with distilled water. This ensures that cooler than ambient temperature air is going into the enclosure and actually cooling things!
