fake or genuine site ?

No online reviews I could find on reddit which seems odd considering this shop is located in Mumbai but judging by the list & prices of processors available on their site I would say stick to primeabgb which is also located in Mumbai. There is also a difference between a genuine site & a genuine site that is recommended for buying products.

You can call them to verify or visit them personally if it is open.

This is the site I know which is genuine apart from Primeabgb
