Bought Gate Opener Aleko AC 1400. Ordered photo-cells. We've hired two certified electricians to install and wire it to the KZB13 mother-board. Neither has been able to get it to work. The instructions are terrible. They both called Aleko support without help from them. We had them send us a second photo-cell, it didn't work, had them send us a 3rd photo cell..Called Aleko support: "we have no no technician available. Can't find any complete instructions on YouTube that fully explains how to wire it. They wired it per the instructions available in the package and it didn't work. Sent them an email explaining what has happened, that is has cost me more than what I paid for it in the first place. That I was disgusted with their product, asking what they are going to do about it......WITH NO REPLY. To say the least: I will never buy another product from ALEKO.
