Iâ€™ve tried suction devices, fixed holders, snap-lock holders, commercial vent mounts - and theyâ€™re never as good as you want them. The stable ones are expensive and often fixed to the vehicle, and the mobile ones are not stable.
In this article weâ€™ll build our own vent mount that fixes the stability problem with four washing pegs. And it takes 5 seconds to mount and 1 to remove. Neat!
And as itâ€™s spring loaded, the pegs can flex a bit and this will allow you to mount the holder instantly in most car vents available.
