Toying with the idea of utilizing the 2 extra buttons on my car homelink (garage buttons). Settled on the LiftMaster 850LM Receiver w/ remotes and now I am trying to figure out whether I should just use the 2450 I/O Linc (Qty. 2) or the Smartenit EZIO2X4. Seeing some horrid reviews on the EZIO's reliability, ease of configuration, etc. and was wondering if anyone had an opinion on one solution vs. another. Any suggestions appreciated.
