Infinite Nado

Does anything know what the deal is with this new brand? They are obviously a clone of Beyblade by the Chinese, however they seem to be a completely legal clone being sold in the same shops as genuine Beyblade burst products here in the U.K. I understand there has been a void of Beyblades here in the U.K. For a while so Nado has come along to take their place. However with the first few Bursts on the shelves now I don't see how it's allowed. I would normally expect Chinese clones to be sold in dodgy markets not high street chains. 

I have bought a couple and I must say... They are pretty damn good. Better than the previous incarnation of Beyblades and the designs are great. Not sure how they compare to burst however as none of my bursts have arrived yet from Japan. I'll do a comparison once they arrive.
We mentioned it in a few topics, like this one: https://worldbeyblade.org/Thread-most-ho...inity+nado
