Very bad experience. I bought a as1200 arm to replace old one and they shipped as 600 . After I got the arm I had my electrician tried to replace the arm but now none of the arms work . After spending a lot of money on the electrician I called aleko to let them know that the gate does not work and aleko has shipped the wrong product . The customer service tells me they are the same product I said ok if it is the same why didn’t you as 1200 as ordered and then this really obnoxious kept arguing so I said I want to return and refund on the wrong product they shipped. She said ok but i will have to pay for shipping and pay restocking fee and it would take about 8 weeks for refund .beware these people are scammers and one should stay away from them
