For the price, I find, however, the processing bad. Some elements do not fit very well and are of different size / length, which does not make the structure. For example, connecting rods were different lengths, one I can install only with a great deal of effort, as it was a few mm too long. Partly it was a bit fiddly, should get the whole.
The feet were missing some Rutschpads, but they were sent to me on request immediately.
Overall, however, it is a good pens (I, however, have no comparison to others). Before buying one, however, it should be clear that it can only be installed with little effort than square and that building for people with little experience might be a little difficult.
