None of these leaks , by themselves , would be a problem. But...they were everywhere and tiny as they were, they all added up to a half full mat come the morning . So, if you wake up on a flat mat and you are going home anyway...no problem, lesson learned. If you are in the middle of nowhere this is a problem. I have had two and a multimat superlite....(they appear to be the same regardless of name), and once the first leak/seam weld pops...thats it...one patch after another. Check other review sites...I have nothing against Karrimor. You just cannot get a mat this light and expect it to be durable at this price point. I thought my first was a one off, thats why i bought another. I bought a superlite on spec...exactly the same. I did not bother returning them for repair . I need reliability and I don`t trust these. I also use a gelert x lite which is a lot heavier but is bombproof.
Z tego co wyczytałem zgrzewany materiał robi się sztywny(...)
Numery seryjnego oczywiście nie posiadam, bo jest to materac z allegro sprzedawany bez opakowania.
