They are fake and a copy of a very reputable US brand of mei tai known as a 'freehand'

I can't find it now but one blog had pictures of one of these minizone mei tais coming apart at the seams; which is very dangerous. The dyes and wadding are not designed for use in baby products and are potentially toxic. Unfortunately ebay don't give a fig about it and many people who buy on ebay don't know that these are not a good example of a quality mei tai hence them giving good feedback. If you want a cheap mei tai from ebay that is good quality instead, try the palm and pond brand. There is also another work at home mum brand on etsy and ebay and they are excellent quality too
