Yes it is
The plastic intake and output pieces are very very cheap other than that its quiet and has a ton of media space and only 20 Watts.
I didn't find the plastic bits that came with my sunsun anywhere near as flimsy as people make them sound.
If I can squish them with my index finger and thumb, I deem it flimsy. The not-so-careful aquariust could be more prone to breaking or snapping components while trying to fit pieces together or take them apart.
Well mine is on a riparium so the spray bar wouldn't work under water level so I had to put in straight up and down. I also had to fill the canister with water because the primer doesn't work with the low water level. Its a great canister for the price I just wish I was better prepared for the plastic garbage. I'll have to make my own.
