I had a cart hose reel in the garage which took up too much space.  I found this type of hose reel that is installed flat on the wall.  Installation was pretty simple.  I like how it looks on the wall and how it frees up a lot of space.  This thing works nicely, only a few problems with dripping water occasionally, but every hose reel I owned has done this.  I'm not sure how this plastic would hold up in full sunlight.  But, for my case, in the garage, i can see it lasting many years
