Get him while you can:
Those who want retribution against this site for ripping the thousands of us off- here's the person responsible- His name is "VADIM OLEGOVICH KRUCHININ" and goes by the aliases of "Vadim Kruchin", "David Kruchin", "David Vadim Kruchin", and "Dave Kruch."

This worthless scrotum-scum lives in Sparks Nevada if anyone would like to take on a little project. But hurry because he's likely to be sentenced to prison, but he's even more likely jump bail to leave the country. Get 'em while you can!

Have they done any good transactions?

The company operates under multiple aliases (Cashforlaptops, CashforiPhones, SellYourCell, etc) and scams people for their devices. If you're worried about not getting your device back or getting the money you want for it, please follow the steps below.
1. Avoid at all costs, if you have not shipped already. Save yourself the trouble and just use another site or sell your device yourself. You'll be grateful in the end!
2. If shipped, log into their online system and keep aware of updates of your device and the emails they send sometimes go to SPAM for no reason. You DO NOT want to lose any updates (emails) they send as this will cause you to lose your device.
3. READ READ READ their Terms & Conditions on their website. When they receive your device, you'll get an email that says Device Received, but wait until you receive the Device Inspected & Valued email. This is where they will LOWBALL the sh*t out of you! However, in their T&C's, you MUST CALL THEM WITHIN FIVE (5) DAYS! Remember this, CALL THEM, not email, CALL them to discuss the offer within FIVE (5) DAYS. Actually MAKE IT FOUR (4) DAYS so they don't ignore your calls on the 5th... and this is NOT BUSINESS DAYS!
4. Once you call them, they will hassle you to let them keep your device and increase the offer without justification. This is where you can decide what is your selling threshold, do you take their increased price or not, it's up to you. HOWEVER, if you feel they are not making an effort you can DECLINE their final offer, and they MUST return your device in the same condition as sent according to their T&C's.

My Experience: I was quoted $881 for my Macbook Pro 13" Mid-2015 2.7 GHz laptop on Cashforlaptops. I received an offer of $136, WHAT THE H*LL! I called to get my device back and the offer went from $136 to $450 to $560 with no justification. This goes to show they are truly trying to prey on people wanting to get money for their devices and scam them out of paying them the original quote. I got my laptop back and sold it to a legit site.

If you're looking for a good site to sell used devices (phones or laptops) try using the eBay Valet program to sell it.

Sold them a working iPhone 5 and was quoted $80. Only paid $5! Took complaint to BBB.
