Is CLEAR really such an enhancement ?

I see the biggest problem in that you have to hold a US passport, another plastic card in the wallet, another fee for security lines (even if it makes it more comfortable).

I had a quick chat with a CLEAR sales rep a few days ago but it seems she was new and had not really all details about live operation.

I would maybe get it if they

-make it available for foreign passports (British in my case)
-ensure I dont have to deal with barking TSA anymore
-are available at all airports of my schedule (even the smaller ones)
