Plus being able to easily move the entire hose cart between the back and front of the house is really useful for me. I'll probably go with a cheaper reel and separate house for the roof. Maybe a gorilla reel, flexzilla hose.
The hose reels are great, but expensive. However, the quick disconnect fittings are a huge quality of life upgrade if you have a hose the you connect/disconnect often. I also have the shut off valves on all my outdoor spigots so I don't have to sit there and crank open the spigot.
