Review on Compact Gikfun Mini DC 6V to 12V R385 Water Cooled Water Pump: Efficient Air Diaphragm Pump EK1856 by Mary Cornett

UPDATE: Pump swap started leaking even after 12 days of use. I've been using this pump continuously for about 10 days now. It had an internal leak today where I was getting about 2-3 drips per second. Luckily I noticed this early enough and was able to clean up the mess. I took the pump apart and noticed that water was leaking out where it wasn't even supposed to be. I checked for obvious signs of leaks but didn't notice. nothing to my untrained eye. In any case, I do not recommend this product as it is not reliable.
