did it, i think mine took 12 weeks, only the bottom row.
I had 1 teeth that was pushed back between the 2 next to it..
4300, they tried to talk me into the upper tray also which I didn't need, that was another 1500...
The only thing is I have to wear the retainer at night for the rest of my life.. some days I dont wear it I can feel it shift the following day
