How long will what last exactly? FYI I've owned another screen whilst having the hazro at the same time (the HP) ONLY once and that was after months of hazro ownership waiting to see if anything else comes out that offers the same IQ as the hazro but without the then limitations/issues.
No offence but I don't think you've been keeping up with the thread and only been reading a few things you want to read and forming an opinion immediately then.
I've also had the Hazro the longest of all the 24" screens I've owned now, it's the only screen that I've repeatedly said to offer what I feel to be (even whilst I had the HP) the best IQ, the best build quality, the best look and feel and the best customer service considering the issues I've reported to the maker and the responses and late night conversations I've had with their people over the phone (they called me even).
Those are the reasons why your reply above confuses me because I never replaced the Hazro, I got the HP WHILST owning the hazro so I could compare both over a few days and whilst I liked the HP at first the issues were not apparent right away abd once they were I made my choice on what I'd keep.
I posted about all this through updates in both HP and Hazro (and the Dell, BenQ & Hyundai) threads at the times of their existence.
