Product review (5 stars): love it.
Arrived on time, installed in 15 minutes (watched you tube video a couple times to make sure I had process clear....seriously though, few wire clips and some RTV sealant....simple) and the next morning the frozen line was cleared. Haven't had to mess with it since (about a month now). With a rec room fridge that only gets used occasionally, this is the longest it's gone without freezing in over a year. Problem solved! love it.
