While doing the same business as NO-Icing in Canada I have come to realize you just can not worry about people that have their own machines. They aren't going to pay tax and nobody is going to do a thing about it here. There has been a recent law not being enforced in the GTA that will now be enforced in the upcoming season. That being no personal skate sharpeners in The City of Toronto Arenas. And some of the private facility's have banned people using them as well. Even Jr Teams. But if you're sharpening is that good people will take the time or find an alternative way to get to you. I personally until this weekend was on the same thoughts as jimmy but now I couldn't be bothered as I am to busy, to be worrying about others. This machine looks pretty decent. My issue would simply be you need a new wheel every 40 pairs? So if you're doing more than your family skates then it is not much different than going to a Pro Shop. And what happens when you have deep knicks? Again you will need a Pro Shop. So while this may do for the average family with 2-4 players in the household more or less it just ends up you will have to go to your regular less often but still go. And when little johnny or susy says I like X-s sharpening better??? But there is a spot for this machine at this price for a small family in the middle of no where. Nothing beats a quality sharpening with a qualified sharpener. That being said a better machine as I said above could even me on a busy day so I would rather work with the company then against it. Good Luck Russ.
