I have two pairs of NOW IPO bindings. I'm quite happy with them. Like Triple8Sol, I've had the logo pop off the footbed. Not a big deal. Just a bad place for a logo that is glued on. The straps are still in good shape and I've to six days on the hills (Five on one set and one on the other).
I've also read some skepticism about the straps especially the toe straps. I'm quite happy with the toe straps. They fit snugly and have never come loose, but I could see from looking at them people questioning them. I much prefer the ractchets and ladders to those on my Union SL binding from last year.
