A opener. Costs half as much, is less prone to errors, and opens immediately and silently. Control depends on what you need. If you only have the front door, the ekey Home Mini is sufficient.
I can agree with guckuck2. Have both versions. The A-opener was significantly cheaper and personally, the automatic, audible locking of the motor lock when opening and closing the door annoys me.
We decided on the motor lock because with the A-opener in combination with fingerprint, the locked front door can no longer be opened. So if someone wants to enter the house after "closing time," they can no longer use the fingerprint for that, but must unlock it manually with a key.
For those who consider the security provided by the 2 hooks (engaging mechanically in addition to the door latch) sufficient in principle, the A-opener is naturally the better choice.
