So just discovered the Xcello Sports Cordless Ski/Snowboard Edge Tuner on Amazon priced at $249.95 and was curious if anyone knows anything about this sharpener as I cannot find anything online. On paper is sounds great, and I like the form factor, plus it is cordless .... but it also sounds too good to be true. More importantly when I try and look up this company online it becomes clear that they are not a ski company, but likely just slapping their name on a ton of different sports gear that they sell on Amazon. Conceptually it operates in a similar way to a Razor tune and may even use the same wheel. Anyhow thought I would toss this out the community to see if anyone knew anything,
