I had a chance to use one of the new CLEAR e-gates this morning at MCI. Of note, it's only available for those with PreCheck and not at the non PreCheck CLEAR space on the northern side of the terminal.

Like all trips through, a CLEAR rep scanned my BP and then directed me to the e-gate and had me bypass both kiosks. The screen atop the e-gate took my photo, asked me to share my info with TSA and then opened up to the gauntlet for screening. Pretty easy process from start to finish, though I was the only person using CLEAR at that time, so I don't know how quick it would process a line of people vs. going to one of the contract TSA clerks.
