It is difficult to know where all the 5 star reviews come: On my bike mount the ball joint is so weak that the Teasi -and at every little asperity middle it does not matter whether off-road or on the road- "gently "to the side or leaning forward! If one does not bother to adjust all the 500 new Navi, then 5 stars, otherwise only one, since the main purpose is not fulfilled!
SUPPLEMENT September 25: A demand for Teasi has meant that you have sent me outright and free of charge a new ball joint mounting. The new bracket is very stable and strong and does not show more the criticisms of my old bracket. My old ball joint mounting probably came from a mounting production ... That's why now by far 1 star to 5 stars !! unrestricted
