Review on 🐠 Adeeing Portable Mini USB Aquarium Fish Tank Oxygen Air Pump - Silent, Energy-Saving Supplies with Added Accessories by Jennifer Dammann

Permanently fails after approx. 3 months; So far I've had 4 or 5 and only one works (we're in our second month with this). from another seller (tip: the green one). Another product has been on sale for 4-5 months, no problems. Now I'm not sure what exactly the difference is, but this blue isn't worth it. You'll spend time swapping them out, sending them in for replacement, etc. This is a good idea and can be useful for those who just need a backup pump, but it's not suitable for regular everyday use. Do not buy this brand from Adeeing.
