JBJ cubey is an all-in-one pico system with a cute name but disappointed owners.

I think JBJ has let their quality control slip quite a bit. I ordered a couple nano-zap UV sterilizers for my nanos and with one the bottom 1/2" connector just pulled right out of the body. It looked like it was wrapped a couple times with masking tape and just crammed in. That's one of the biggest issues with this hobby is that you think you're buying from a quality manufacturer and expect a product that at least WORKS but then you wind up with something like this, or a Coralife Dual Timer, or Kent Carbon etc.
