DANGEROUS FOR SERIOUS SKIERS!
The unit only comes with 3 springs and serious skiers will “bottom out” (hit the floor) and possibly fall out/off and get injured. I called the Company and they wanted me to buy two more springs even though the unit only holds one more spring! If the Company was interested in selling to serious skiers they would supply 4 springs in the first place! DONT BUY IT! MINE IS BEING RETURNED!!!!!!!!!
