This is an ok item i was impressed with its small size and the adjustable flow rate in my 30l but i found that the filter comes apart far too easy and the filter doesnt seem to be making the water as clear as it should be

This little filter has been great cleared all cloudiness from my tank after 10 minutes of switching it on the filter works alright but the suction pads are a bit too weak and therefore they do not stick to my glass tank very strongly
