I must admit first experience with dell they are pretty useless ... doubt I'll ever use them again, tempted to get the lg ips for £650 instead but as I've waited this long might aswell wait another (insert random number here) months. Just sucks that people over the world are ordering and getting them 2 weeks later and if you order now allegedly you will get it in 2 months.
I have only had one monitor from them but I swapped it three times due to really bad glow and they would always send me one out before I'd return the other one. The service was great.
