Got my super cheapo Flites today. Can really tell the difference after looking at some NXT's at the board shop today. Mounted and fitted in a matter of 20 minutes. Size 11 boot and they fit like a glove.
Not having any issues locking in yet. We'll see how it goes on the hill tomorrow. Supposed to get a few inches along with some freezing rain. Should be an interesting experience.
RX, I'd recommend making sure the bindings are centered. Pull down really hard while standing and make sure to tighten/loosen the cable. Mine felt too tight until I loosened it. Other than that...make sure your boot is ALL the way back against the high back before you adjust the bindings. Little things, overall...but issues that I fought through quickly in the process. Hope you get it set and shred. Let me know if you have any luck.
