3 years and 3 months
3 years and 3 months, thats how long the arm lasted. The housing broke in half, arm went to wobbling and wollered out the screw part on the arm. After 1 year We had problems with the phone app. Support said it was my phone, except my 3 sons live on my property and my mother, nobodies phone worked. Had to reset the system, delete all keys and assign new keys. I lubed it once a month with white lithium including the gate hinges. It was decent for 3 years. If you want a lifetime gate go with one of the higher quality companies. Support is dodgeful at best, and warranty is up to 24 months.
