3 Dead EdgeRouter Lite

Let me start by saying I love UBNT products. I have about 30 EdgeRouter X's at different small businesses and have never had any issues with them. 

On the other hand I have purchased about 5 Edge Router Lites and I have since replaced them all with Edge Router X's. 3 of the 5 lites died within a year and a half of being installed.  

Support will not RMA because they are past the 1 year mark, I am pretty dissapointed since there is obveously an issue with these. I have searched the formums and I see a lot of people having similar problems. 

any recommendations of what to do now? Use them as paper weights? Your support team very quickly brushed me off and it would seem like you guys could at least replace them for the X model. I don't think that is too much to ask.
