Hmmm.... Interesting website.
It looks like one of those companies that is full of generic accessories. Pretty on the outside, but with absolutely no quality control. And, some items will be good within the scope they are purchased in. Others will break or be non-functional almost immediately.
And, then there are the review battles. A search for the bike site above brings up a company "LOOX". Every one of their reviews for the bike company above is a glowing reviews complete with pictures. Well, except for one of a broken product that seems to have slipped through. I can't say if the reviews are real or fake, but it appears as if the published reviews are carefully selected.
