Well .... 116

A Window cleaner is in the range of "OK" category falls just. Here the manufacturer could have taken a much longer stick. My aquarium is 60cm high and here it is not possible to reason the algae to remove to the disc without the whole hand while wet. Also the joint and the mobility of the blade attachment is not really optimal. Here is a slightly smaller blade and more stability would be asked. This could be more pressure exerted on the wheels and thus better remove the algae. Even when blade attachment itself it would have been better for the user to construct as the commercially available razor find the mount use. Unfortunately, one is forced to take only their own brand of Tetra that naturally reflected in the price. I personally would not buy me 2x!
