Hi Everyone. Our facility has been using about 500 Sunray 270's for a few years now. We are becomming increasingly concerned though about the high failure rate (about 1 in 20) of these devices. It seems that they start to fail after only a couple of years or less. Also heard that Sun are going to end-of-life the 270 anyway. Has anybody else experienced high failure rates with the Sunray 270?
