Review: EDIT: I installed this item one week ago today. It has worked as advertised. While returning from running errands this morning I received a notification on my phone that the power was out at the house. The first real world opportunity to see if this piece of kit is worthy of the cheddar. I arrived home in about 10 minutes and confirmed much of the neighborhood was out. It's hot, DAMNED HOT, outside today and this will never do! It took about 15 minutes total time to get the gennie up and running and arrive at the moment of truth. I flipped the breaker for the gennie and powered the panel, then energized the furnace circuit (Ecobee thermostat controls), then energized the A/C circuit and waited. It took right at 2 minutes for the Ecobee to come online (wifi is on UPS) and call for cool. The fan on the A/C started first, seconds later the compressor started, the gennie shouldered the load like a CHAMP, and the A/C was running! I energized the rest of the circuits according to my emergency power plan and monitored cycle performance in cool air conditioned comfort. "I love it when a plan comes together!", Colonel John "Hannibal" Smith. Purchase with confidence! OE Review... Meets and exceeds expectations. Simple, straightforward four wire installation. Easy enough for a handy DIYer. They even have a short YouTube instruction video! I purchased this so I could have AC when the power goes out. I have a 4 ton HVAC that drew 106a inrush before installation. Too much for a modest portable generator in a power outage. After 6 learning cycles it only pulls 26.xxa! A bona fide 75% reduction in startup draw! It’s also much quieter now too. I highly recommend!
Review: I run two geothermal heat pumps - one 6 tonne and the other is 3 tonne. No more harsh startup sounds or light flickers on startup. On first startup in learn mode saw 66% reduction in startup current.

My issue was the lights would flicker whenever the AC compressor would start. The Micro-Air Flex has solved that for me. I think it does a bunch of extra things that will benefit me down the road, but for now my problem is fixed! Easy to install. Instructions were very good.
