I love the expanding hosepipes - they're so light and easy to move around with, and never get kinked!
That being said, they don't seem to last as long, but that could just be my fault!
Just a few things to bear in mind if you decide to buy one:-
1. They never expand to the length they're supposed to reach to, so buy one longer than you need;
2. Look for one with brass (rather than plastic) fittings, and preferably double lined;
3. Wait for it to fill before using it - people complain about lack of water pressure, but you won't get good pressure if it's still filling;
4. Don't overstretch it, as the inner bladder can become detached leading to hours of endless fun trying to find it and re-attach (easier to buy a new one tbh);
5. Try not to walk over it when it's deflated to avoid damaging the inner lining.
Despite all of the above, I wouldn't go back to a coiled hose now and they're a blessing for anyone with mobility/strength issues.
