I always travel with two large suitcases that are almost always filled to 50 lb capacity. This has done WONDERS for me. I didn't want to give up my old suitcase that had a strap attached to it so I could snap on a second luggage and move around baggage claim with ease.

I haven't used this with the three max capacity but I don't see a problem with using it.  I did read the other review that suggested to use the last two links when attaching two pieces and it DOES work better than using that C clip for bag 1.

It's quick and easy to attach and remove from your bags. When tightened as much as possible, it's very easy to maneuver your way through crowds and baggage claim as long as your wheels are good on the luggages. If you have crappy wheels or wheels that are not 360 degree maneuverable, you might have a little difficulty turning in tight spaces.

This is a must have for those who travel with lots of luggage.
