I had ordered this product because of the good reviews and was disappointed beyond measure. The main problem is not the moderate processing among others unexcavated degree, but the net size. The edge is not only high, but also around! Furthermore, the long outer edges are not straight but oval, thus going from the outer dimension space lost and you can not put the toilet and sensibly on the wall.
Exterior dimensions specified: 50 x 40cm Exterior dimensions Actual: 50.5 x 41cm (a handle is for bad processing slightly) Not hidden internal dimensions: 38 x 28cm !!!
A small to medium sized cat of about 4,5kg will find hardly any space to turn.
The high margin is a good idea, but I would find it even better that product from Amazon to specify reasonable for Fehlkaeufe spared.
