I purchased a Zevroid 30" 30QU Plus 2560x1600 S-IPS WQHD monitor from Bigclothcraft on eBay about 6 months ago and recently bands of distorted colour started flashing across the screen intermittently rendering the monitor useless. Bigclothcraft ignored my emails so I opened a Paypal dispute which was recently decided NOT in my favour with no explanation. The EBay and Paypal guarantees turned out to be useless. So the 6+ month usage cost me $570. Bigclothcraft listings state "We guarantee 100% satisfaction for you." That's obviously not true. They won't even give me the courtesy of a response. Bigclothcraft has excellent seller rating but that doesn't reflect their actual performance when a failure occurs some time after the purchase. Initially the monitor was fine so good feedback is given, after it fails nothing can be done about the feedback. Be aware of the risk you're taking if you buy one of these cheap Korean monitors. $570 is a lot of money to gamble. The Seller, EBay and Paypal guarantees may turn out to be advertising hype like in my case. Better to get a monitor from an established manufacturer like Benq which has a 3 year warranty.
