Review on JAKKO Portable Mini USB Aquarium Fish Tank Oxygen Air Pump - Compact, Silent, Energy Efficient Compressor for Aquariums by Jessica Watts

If you have a fish and transplant when you need to put the fish in buckets, you will have to move the aquarium (even to a new house) or you just have a Nano 10 or less and you need some serious bubbly action. Buy it! This is how you prevent your shisha from jumping out of said buckets and save your tail when your landlord hits you and you have to move. I can't say much about durability as I use it to calm fish during bucket breaks or cleaning. Airflow is extreme with an air stone and included hose, so grab a regulator or just squeeze the air hose and secure with rubber bands or something. And it's pretty damn special when you restrict the air a bit.
