I had a 3 screen setup and one of the display units started have some strange, maybe heat related, highly intermittent issues. I sent it in with as much info as possible since I understand how hard intermittent issues can be to track down. I got a call a few days later saying it was fixed... I then asked to talk directly to the tech since I kind of expected a "cannot duplicate, works fine" note to come back with the unit. Imagine my surprise when he explained that they had a shaker table and some sort of heat setup for environmental testing and were able to reproduce the problem! They found the issue, fixed it and returned the unit to me all within about a week. Only cost to me was one-way shipping of the unit to them!
Great company, great people, great products!
