I had clear for a year or so. Prior to pre-check, I could see significant value in it if you regularly flew out of the airports that it covers. I flew out of SFO T2 a lot and it was a nice timesaver, plus they escorted you right to the table to put your items down (also would get a bin for you). In DFW, they weren't at the most convenient checkpoint for me. On occasion I would move down a checkpoint to use it, but here they would just have you cut the initial line and then you would wait in a line for the actual security check (also this checkpoint had the nudescope while my normal one was just a magnetometer).

Now that I'm 100% pre-check, at most I wait 2 minutes at SFO T-2. There's almost no value to me in Clear anymore.
