Original Hormann remote has so bad blastic. You replace 2 batteries and one drop on the ground, and the remote is already in pieces. This replacement is Superb! I used M2.5 screw from this set: https://www.aliexpress.com/item/4000056753202.html And M2.5 brass insert from this sets: https://www.aliexpress.com/item/1005005477576624.html because thew have oposing fins/groves. What I would really like to see, but dont find time to do, is to add some kind of protection from accidental presses.
