Problem: Every time I rip the 50ft extensions out of the 100ft extensions, they always twist together no matter how carefully I roll and hang them . .Solution: Wonder Extension Winder. What I love about it is that it makes working with these extensions so much easier and gardening gets done with a lot less swearing. No more knots, no more confusion. What I don't like about it: First, the instructions have to be updated. Some of the things I was told in the instructions were already done with the device I received. It was a little frustrating trying to figure out what phase of direction the device was in so I could complete the build. Second, when you mount it on the wall, you can rotate it 90 degrees to the left and 90 degrees. -ish degrees correct. It's great when you use it. However, if you're standing in front of it with one hand on the brake and the other on the reel lever, trying to reel in 50 feet or, God forbid, 100 feet of line, and the damn thing swings back and forth as you turn the lever, you want the kitty meeting. There really has to be a way to quickly lock it to prevent this from happening. That's the real reason why I can't give 5 stars. Apart from that I love it.
