We bought this for more hose length to maintain tanks that are far away from water sources. One reason I chose the Aqueon hose to begin with was the relative stiffness of the hose. I don't want kinks in the line while I am stringing water across the house. However, the extension hose is NOT the same tubing that was used on the original and does have a tendency to kink. This is not to say it's as flimsy as the cheap tubing you can buy at the hardware store, but it doesn't hold up the way the original hose does. I don't have an alternative to suggest, but do keep in mind that it's a bit flimsy.
