Practical and sturdy

Used daily for ten days, no worries met.
Huge sucker! Once attached, the support does not move. The locking lever by the suction cup is very effective. This is dramatically more efficient than screw tightening, even on more expensive media.
The axes turn and lock with push buttons, very convenient! All that remains in place and can easily be adjusted (in case of sun reflection for example).
Small legs upright avoid tightening the clamps like a nag. Good because these clamps are the elements that seem the least resistant, compared with a support that exudes strength.
Very compact rack price! Until then, happy with this purchase!
