I don't think chinglish means its definitely a poor product but I can imagine there is a steep learning curve to the product with so many features combined into it. Seems to a be a reasonable review here;

Lots of western brands import generic Chinese lights and cycle computers which they rebrand to sell in their stores etc.
Halfords,
Decathlon, Oxford, XTC etc. Most of the US and European bike brands don't actually make anything at all themselves but are reliant on factories in Asia. Admittedly they would spend time vetting which factories they use but the same factories typically also sell under their own brands. I mean sunding cycle computers are rebranded by a huge number of western brands.
