I spent a while fixing these bindings, adjusting them to perfectly fit my boot. But the rear release lever is painfully hard to release. On the slopes I spent more time struggling with it than it would have taken to strap in and out of normal bindings. Also, Once you adjust the uni-strap position to your boot so it's tight, then it's almost impossible to get your boot back in there all the way under the toe end. You can't do it sitting down and standing up is almost impossible because you have no leverage in the snow. So if you're not all the way in, the back won't close. Also, the small ratchets on the straps are impossible to operate with gloves on and very hard even with fingers. They are tiny and take enormous fingertip pressure. I switched back to my regular bindings the next day and was in and out much faster!!!
