BenQ Projecteur Lu935st Full Hd

I have a client who purchased three of these units. One failed within three months. Benq sent a replacement which did not match the color or brightness of the others. Then the original two began color drifting apart from eachother with minimal hours and within the warranty period. I was promised a matching set of three would be sent out in exchange but they never were. Benq refused to honor the warranty and ghosted the calls. After months of discussions with their aloof management team they refuse to acknowledge that there is a QC issue with this product. I specify tens of thousands in projectors each year and can unfortunately not recommend Benq any longer. Do not buy the LU935ST products - go with the Optoma ZU607TST instead.
