Great customer support!
I always love the lights and heaters, the lights really help my plants when starting a new tank and reduce the melting by a lot! I got a filter, the usb sponge, to try for the first time and unfortunately it stopped working within a couple of days, but getting a new one sent out was super simple! Ginger from the customer support team was super helpful! The replacement filter works great and I have had zero issues since!
