Therefore, in my view, the five stars are appropriate. 150 euros is certainly a high price (the cheapest products on the market, there are 50), but by the quality of the price is justified.
Before you buy this product, however, you should be aware as the spatial conditions are exactly and how you want to build it.
The background is that the connection of the grille takes place by two screws, a wood screw up and screw down. With the latter, the two grid parts are connected at the bottom and screwed to the base plate, which are also locked in a respective hole in the round flat spots. Through the two screw and the entanglement of the grid members on the other hand a high degree of state stability. Nevertheless, in order to ensure a flexible structure, the manufacturer has provided in the flat spots several holes, thus can each two parts are mounted at an angle of 90,105,120 or 135 degrees.
And here lies a small - but detachable with school mathematics - task, on the way too thin assembly instructions completely ausschweigt itself. This does not address the different installation options, but leaves the buyer to worry about the possible angle combinations.
Example: Full structure as playpens. Because the documentation is no statements about the possible combinations have to be calculated mathematically possible combinations of Verschraubungswinkel. If you want to use all six parts, creating a hexagon in the (known?) The sum of the interior angles is always 720 degrees. The sum of the selected Verschraubungswinkel must therefore 720 result. The simplest solution is to screw all the parts at an angle of 120 degrees (going since 6 * 120 = 720), but that is certainly not ideal for all rooms (as so nearly square space is required).
The I first sighted solution (4 * 105 + 2 * 150) is mathematically possible, but goes with the product is not practical. since there are no holes for a mounting angle in the 150 degrees in the stand plates. Ultimately, I decided for the combination 2 * 4 * + 90degrees 135Grad, a prima appropriate in the living room combination (you can with laws of geometry - in the case for example with the Pythagorean theorem - the math that a depth of 217cm and a width of 127cm results -> because the after Augemaß was closely I've even done that ...).
Even more diverse are certainly possible combinations build the grid members as "Space Lock", ie with two wall connections, but since I use the grid as a playpen all I can do nothing (the assembly instructions but not much ;-)).
To sum up, a really high-quality product, the material quality, the five star justifies sure, but it could really benefit from a better product documentation.
