Over time, they acquired some popularity (probably due to both their firmware evolution and their present customer support) but it was nearly impossible to distinguish their products from others if you wanted to buy from them.

Another small change will be the presence of the "IR Night Vision ..." sticker on the focus rim but this is already common amongst the clones.
