The red sector went out completely after 3+ years. Sent it in to Lopo (they don't even ask for warranty info) and they sent another one. This time two rows of the green sector were bad out of the box. So they are sending another one, with the first replacement going back as a followup. Will see how this one does, but does not speak well for current QC. They did promise to test this one in house before they sent it to me, though.
