Replying to S 810 ti

so I found a pair of old s810 ti in my garage. one blue and one gold, so I inverted the toe piece to make a mix. it is sure that they are better than the demo bindings WITH lifters that I had. but I had to put a 3mm lifter under the heel piece because they didnt have time to look for the tiny screws and my skis arent thick. I searchbared it. In 1 thread, it gets totaly bashed at, even worse than markers and in the other one they are good. so what is it?
