I've had levers, mudguards chainguards, toolboxes and tanks from India.
The levers were pretty good but everything else required fettling to fit it correctly (or in some cases couldn't quite get it to fit right with the skills I have.. ). Sometimes, it's only minor fitting changes and sometimes much more - it varies so much
Yes, I'd have have paid more for something made correctly, which fitted, but it many cases it just isn't available or the wait would run to over a year (or more). Yes, i could spend my life trawling ebay, autojumbles and asking about for an original (probably in a bad way) with or without result.
My expectations are low, of the Indian things, along with the price.
And it's these factors which keep these sellers going - I know there is a high chance it's going to require messing with and I accept that as it's cheap and available. On the occasions, it's a good part then I am very happy.
I wouldn't trust electrical or mechanical parts from India, but sometimes its hard to know the origin of everything you buy in the UK.
