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.

Reviewer: Mike Harbor from Mt Juliet, TN United States  
The replacement board got the gate up and running flawlessly. This is my third good experience with Mighty Mule and their staff. The technical staff is knowledgeable and take the time to be sure you understand. Thanks.
