When you talk to people that have upgraded to electric reels, they will quickly tell you that they would never go back to manual wind up reels. This photo shows that with the press of these buttons, you can now effortlessly wind up your lengths of hoses. However, one thing that needs to be noted is that there would be different resistance put on the electric motors, eg. If you had only 1 hose length out, the motor would wind up too quick as there is hardly any load. And if you have 10 lengths of hose out, the motors would struggle. The box on the far right hand side fixes that. You can dial the speed of the motors depending on how much hose you have out!
