Whenever you are trying to sell your gadgets, avoid Cashify at all costs.

Cashify will initially lure you with an inflated value with their preliminary check on their website . However, upon the site visit, their "experts" will unnecessarily try to push down your device's value no matter how well maintained it has been. Most people not wanting to go through the hassle with another buyer will go ahead with it and lose out on getting more value for their device.

On the other hand, most of the exchanges (unless powered by Cashify itself) have relatively lower standards in the wear and tear assurance and you might end up getting a better deal.

I have personally experienced this while selling my iPhone 6 with Amazon (tried Cashify too) and can vouch for it.
