We have 240 of these computers around and so far 3 screens have broken. that's more than we paid for the new block. It was an easy install and very economical. We already had one installed and it's been up for 2 weeks now - we'll update it once it's back installed and we have more time. UPDATE 2/15/16: We installed 3 of these and they all worked fine. We have ordered 3 more to keep stock.
