This suitcase that's attached to a scooter impressed millions last year.
The TSA-compliant carry-on allows its rider to get to his or her terminal faster.
Viewers debated on whether the invention would make travel easier or cause new problems.
Hi I'm Carl.
And I'm Chelsea.
We're testing out inventions to see if they live up to expectations.
We're here to find the answers to the most important questions.
It's cool...
But does it really work?
You're in a crowded airport or crowded train station.
All these people around.
And you're gonna have to try to bob and weave so it's a lot of starting and stopping.
So I don't think it really takes away too much time.
But the companies claim is that this suitcase will get you to your destination 50% faster...
...because it has a scooter attached to it.
And I think that that claim will be accurate
I thought it was nice and compact.
It didn't seem as bulky as I would have expected.
This is where you put your other things... and stuff.
That's where you put your things and stuff.
You know, I could pack for three or four days with that thing.
Bobby came up with the idea of our scooter luggage.
It's because there was a time when the flight restrictions were getting very, very tough.
We decided let's make a luggage trolley.
Concerning the folding up, it's absolutely simple.
You have a leash here, you pull it and...
...it goes together within a second.
Come on Chels.
Put your foot on it and pull up.
Put my foot on here.
Okay, I'm going somewhere.
We decided to take our scooter suitcases to one of the busiest travel hubs in New York City:
Grand Central Station.
Like we got looks all day from people.
Awesome yo, that's a great idea. You take care alright.
Micro.ms, perfect thank you!
Please stay tuned.
After the break we're taking the scooter suitcases to one of the busiest places in the world.
We brought the scooter suitcases to one of the worst places on Earth:
Penn Station.
About 650,000 people pass through here every day.
That's more than JFK Airport, LaGuardia Airport and Newark Airport combined.
The plan is to find a long crowded hallway.
We'll travel the distance twice: once walking and once with the scooter.
We will time ourselves on both trips and find out if the scooter cuts our travel time in half.
On your left sir, thank you.
It took off a solid 20 seconds.
I think you can get from one place to another very quickly
So it solves one problem but it raises others.
So the suitcase scooter might not get you to your destination in half the time.
But every second counts and it will get you there faster.
The suitcase scooter is difficult to steer in large crowds.
But it is a fun way to travel.
Next week on "It's Cool, But Does It Really Work?"
Excuse me!
Does anyone have a hairy back?
We're testing out the back blade.
