Which is the Best Site/App to sell your old or used gadgets?

Sharing my personal experience and looking forward to explore more options! Thanks!

The all new Cashify App (https://play.google.com/cashify) is quite amazing. Caught my attention during the recent buzz about their exchange programmes. I had a Samsung Galaxy Grand Duos which is more than two years old and I was looking for a right platform to sell it for the best price. I tried downloading the app which is only available for Android OS as of now and might be available for iOS soon I guess. Frankly speaking, I was quite amazed with what it does. Introduced by ReGlobe - a firm that buys old and used gadgets through their buyer network, Cashify is an all star that offers convenient, secure, fast & easy way of selling old gadgets. You get a price quote within a fraction of seconds once Cashify finishes to diagnose the mobile automatically. It's your mobile's personal doctor and tops the charts of my favourites' list. I got INR 4200 for my phone which was higher than what the other portals were offering! Also a free pick up of phone in addition. It's a must try! I am sure everyone will enjoy the steps that are included in the self-diagnosis process! Views are my own! Thanks!

What Sci-Fi gadgets do you want to see in real life?

There's a lot of really cool tech on TV shows, films and books, like the Holodeck and Transporter from Star Trek, or the Babelfish from Hitchhiker's Guide to the Galaxy, and so much more.
