I have one, but I didn't take into account that I have many things plugged in by my machine to the outlet. Then there is the fact that it is really cluttered also. I don't have room for mine and my winders work fine on my machines.
If you want to buy mine cheap just let me know. I have it listed on Craigslist, but no offers from Rockford, IL.
