DO NOT PURCHASE August 17, 2016
Reviewer: Disappointed in Mighty Mule from Clarksville, TN United States  
This control board is nothing more than a source of frustration.  Have purchased four R4211 ($250 x 4 = $1000) control boards in two years and all have failed with thunderstorms in the area.  Followed all GTO installation instructions to include lightning protection technical sheet; quality surge protectors; turning unit off and unplugging transformer before storms arrived.  Read other site reviews and this is a well known problem with GTO openers and GTO does nothing to back there product besides selling replacement control boards at a premium that will fail you.  The correct fix would be to design a control board that can operate outdoors and does not fail when it storms.  Recommendation to GTO is to replace failed boards one for one at the cost of reasonable priced shipping.  If nothing else, offer a multiple discount on sure to fail R4211 control boards (Buy 1 get 3 free).  Do not purchase this headache/heartache producing equipment.

Great Product and ask more questions when ordering March 4, 2016
Reviewer: Mishan from Los Angeles, CA United States  
(IN SHORT: Ask for a new spade with each battery purchase).  I had a problem recently with a battery that needed to be replaced.  Before ordering, I actually went through the reviews and looked at what other people's experiences were.  I saw that some had problems with one of the double spades breaking.  I had not, but reading that still made me ask the sales rep when I called in to order a new battery.  The whole reason I called, instead of just ordering online, was because I wanted to know more about the spade connector, or anything else I should be prepared to replace.  The sales rep said not to worry about anything and that was it.  When the battery arrived and I was installing it, the double spade connector broke.  I have not been able to find a replacement anywhere.  I've been to more than 15 stores: auto, audio, hardware, software, electrical supply, tools, etc.  Nobody has this piece.
