Recycling of electronics

Used electronics gadgets have some value left in them and there are number of companies offering to buy used electronics.

There's no question that smartphones have become a major investment for consumers. And with the pace of innovation accelerating, it seems like the minute you buy one smartphone, a newer and better one has been released. Reselling old devices to help pay for new ones is a great idea, but as I just pointed out, consumers must beware. A whole new industry has popped up to help people unload their old devices for cash, but as with all "gold rushes" there are often some less reputable establishments mixed in with legitimate ones.

For most products resale value is pretty low but for Apple products it is higher as there is demand for old Apple iPhone and Apple computers.
