I've been using them for a year, these specific ones are better than the newer version with the 4 buttons and fit better on a keychain. However, it requires a firm press and a large surface area on the button to register, which is why I gave it 4 stars

If the door opener motor is installed low, it has a range of less than 20 meters. I have noticed this as I have it installed low on 3 doors. I don't know if it improves if someone has the motor installed high. Anyway, it doesn't have a maximum range of 150 meters, not even as a joke, only maybe in ideal conditions with clear visibility between the remote control and the motor.
