Out of 5, 3 were bad, out of 2 were good, 1 was extremely questionable, by which I mean you can get it to work by applying pressure to the surface. Delivery was rocket and the price is very good for 5 units.
They took almost a month to arrive because they came from China and had to go through customs . However, despite the wait, they were excellent and reasonably priced. I bought them to replace the cooling devices in the mini cooler.
Pros
★ MOST OF THE BEST MADE OF Semiconductor material that was sandwiched between ceramic plates and had no moving parts
Product works well. I've seen some info that says which side is the hot/cold side and which side the seal is on - you can't trust that - the only way to be sure is to connect the leads to the battery (a 12 V car battery is enough) in the correct polarity for a few seconds and you will feel which side heats up. However, if you screwed up and already installed the cooler on the heatsink incorrectly, you just need to reverse the polarity of the wire.
Pros
★ COOL ICE IN MINUTES OR HEAT TO BOIL by simply reversing the polarity.
