I did buy two pieces from an Amazon dealer just to try it out for myself and another player here, which cost us $60 total, $30 apiece. He’d been previously using Taom 2.0 and had heard great reviews about the V10. After one night of playing with it, I placed my order direct from Taom, when I realized I could get a nine piece box for roughly half the $30 per piece Amazon price.
I’ve previously been using magic chalk, then Taom Pyro, then Mezz Exceed chalk. All of them in my opinion better than the previous, and all extremely clean. The Taom V10 is far superior to all of those, IMO, so the price for me really wasn’t a major issue, particularly considering how long it lasts.
