I installed DC Moto GFM-905 a few weeks ago on my stock gate from developer for my terrace. I opted for swing type instead of folding with roller bar type (stock gate is folding type). I was told folding with roller type will create more problems in the future. (Stuck roller, bent roller bar etc.) Just right after I installed I saw some technicians repairing my neighbor's folding type gate on the bar (aka railing) at almost 10PM at night.

1 problem is the alignment when the gate closes, sometimes a bit offset and cannot lock with horizontal slider through. The stock gate itself also not perfectly aligned and starting to rust at certain areas even after fresh paint job a few months ago due to paint chipping off due to abrasion during usage.
