Nintendo Alarmo is most sensitive if you leave the bed from the opposite side of the bed. So this wall mount helps to place Alarmo on the wall side of your bed.
Use double tape to moun it. The angle of the holder is disign for a full size bed. I haven't tested with twin size but it should not have any problem. There is a slight tilting down on the angle, so that you can mount this higher than the 8 inch / 20 cm that Nintendo asks you to.
