Used the new customs kiosks at ATL
 

How long have the kiosks been in place that replace the customs forms for US citizens?

We were apprehensive when no forms were distributed on the plane and we saw the rows of kiosks before Immigration. However, the line moved at the speed of the Immigration officers, so no hold up there despite our unfamiliarity with the machine and the process. Spotting an open machine because of the layout did slow the line. It took several tries to get the kiosk to read my passport, but it read my husband's on first try Then lining up face for photo took a short while after the long flight when my eyes don't focus so well.

It doesn't save on paper since it prints out receipt to give to customs and it didn't speed the line at the customs exit, but it does create a database.

I just used it entering the US via DFW. It was so easy. We had been given the usual customs form on the flight, but when I handed my passport, the immigration kiosk form, and customs form to the customs agent, he just took the kiosk form and said the other old customs form was a "souvenir". My bags were first off and I had no lines to wait in. The photo was awful though, but who cares?

We used them entering the US in Houston, and it was a PITA. The machine read our passports, but the system did not have our flight number, so after standing in line for a machine, and fussing with the machine for a minute or two, we were told, by the machine, that we had to go stand in the other line, with all the other people from our flight who had the same experience. When asked about it, the agents just shrugged and said "it happens".

We were not impressed. Looks like the government paid some contractor handsomely for totally unnecessary equipment.

When they work properly, the kiosks are huge time savers. The system knows what flight you just came in on and displays that information.

I've used the kiosks a couple times coming into Miami. I like them, quick and easy. The photo always seems to be the worst but I can live with that if I get thru faster.

Except when it doesn't. Then, you've lost time; end up at the back of a long line when you could have been at the front (had you known); and that line moves slowly because the number of humans working has been drastically reduced.

I used them at IAH in Houston on July 4 and they worked fine. I'm pretty sure I would not have been able to make my connecting flight without them.

"Except when it doesn't."

That's my point. It usually does work fine. It sounds like you had a one-time bad experience with it. :(

It is an limited version of Global Entry and occasionally there are hiccups.

I actually had no idea these were being put in place and was quite surprised to find them when I pre cleared US customs at Vancouver, BC Canada.
