They are fraud just making fool to customers, first they send faulty part to there customers (its look good but its faulty) and when customer raise replacement request they ask to send that product to them by courier only after that they will verify and simple say this is physical damaged so not cover under warranty, if still you want your product back then you need to pay courier charges to them otherwise forgot your product.
So i never suggest to you guys to make any order from maxbhi.com.
