Hey, Marsidarsi,
Sorry to make you feel offended, it definitely wasn't anything against Polish people. From my experience (and it's quite extensive, Polish strollers-wise), Polish strollers are often, if not mainly, made to be budget friendly. That also means that the materials are often cheaper, or the features are a bit limited, which is logical as to save money and to sell something cheaper, you need to fund cheaper resource(s), too. So, not cheap power, but more like, materials and designs are often on the cheaper, simpler side.
Again, nothing wrong with that. But it is true that many Polish systems especially have elements that could actually be better, and also the seat part design often is on the basic side, not always the most practical. That is depending on the brand, model, and price range, though, and definitely isn't meant to be offensive - more like, honest. Just look at brands like Babylux / Raf-Pol, Dorjan, Baby Elegance, many Tako and Bexa models, etc., and after really looking at the details, you might see what I meant.
