Testik zaujímavý. Akurát neviem do akej miery verit výsledkom testu, ktore robila firma, ktorej kluky su najlepšie v každej meranej kategórii.

ten test nerobila ta firma, test sa len robil na jej strojoch

To si myslis, ze nechali nejakého chalana len tak nech sa pohrá s ich strojmi. To ze pri tom bol a fotil je mi jasne ale ci aj nejak vstupoval do toho ako a akou silou budu zatazovat uz neviem. Ak aj neskreslovali namerane hodnoty priehybu, tak je tu este stale moznost kazde kluky zatazit mierne rozdielnou silou.

tak potom nema zmysel aby si si pozeral hocijaky test hocicoho, kedze to co pises moze spravit lubovolny testovaci subjekt

Mne sa ten test celkom pozdáva, údaje z neho sú odlišné ako na iných stránkach výrobcov, kde samozrejme každý preferuje svoj, ale ten zvyšok má inak prehádzaný. Navyše aj meraný údaj vyzerá byť rozumne zvolený a nie len nejaké astronomické čísla síl, ktoré majú bohvieodkiaľ.
