Q. Is it easy to move the Retractable Hose Reel from one tap to another?
A. It sure is!  You simply turn off the water, disconnect the leader hose from the tap and pick it up using the 2 handles.  Please keep in mind that the longer (and therefore bigger) the hose reel you buy, the heavier it will be to carry around.  Water left in the hose gets very heavy!  For most people, it's easy to handle the 20m model. The 30m is a bigger unit and heavier to carry around. 

Q. Is this bracket suitable to use with the Classic Series of Hose Reels?
A. No it is not. Both the Evolve™ and Classic Reels have their own bracket design and cannot be used with the other. The good news is that both brackets use the same screw pattern, so if you are swapping from a Classic to Evolve™ there is no need to drill new holes. 
If you do require a Classic Series bracket you can find them here.
