Looked at reviews and from what I've gathered the wave heads are good for the price but everyone hates the app. Curious because I'm setting up a Low Boy from ZooMed and want a gyre since the tank is shallow and all and alternatives are either random never heard of amazon brands or pretty expensive for 1 pump. Just curious what everyone's experience with Jebao is weather its good or bad (with some context) or if anyone knows of a reliable cheap gyre. Bonus points if you're able to find replacement parts for the Jebao or other cheap powerheads! (also curious if some other well known brand gyre replacement parts would fit such as guards or replacement blades, for reliability and aesthetic reasons such as changing the purple blades for red like most others.)
