Sven at freiluft-blog.de has been testing the Quadratic
Overall, the Quadratic tent system left a very good impression. The processing of the individual components is excellent and the system generally well thought out.
No matter which combination you choose, the price is quite fair for the offered quality and the unique modularity. If you travel a lot in different regions and / or in all seasons, such a flexible tent system could certainly be worthwhile.
