Spark are the best. I highly recommend it

This has been a game changer since day 1! Within the 1st week of ownership, I've cut 10 pairs of skates, and have tried numerous different hollows for my kids to find their best cut. If you have a hockey family, this is the #1 purchase for you to make!

My 9-year old grandson has been playing hockey for a couple of years and my son was complaining about how often (and the cost) his skates needed sharpening. So, for Christmas, I bought him a Sparx sharpener, and he said it is pretty sweet, the tech is slick with an app, and you can save profiles, preferred rings, etc. And it tells you the life of the grinding ring/air filter. Very good Christmas present!!

Easy and accurate. What else do you want? Portable! Right! It’s that too! This thing is so easy to use it’s ridiculous. Did the math as well and it pays for itself in a little over a year and a half. We had a line out of our hotel room door at our tournament this past weekend of our players and their siblings wanting to get a fresh sharpen. Great product all around!
