Tuning Must Have
This vices are a must have for your tuning needs. I have not used anything else but I can't imagine tuning without these. The suction cups hold your board in place as you are waxing and cleaning while the seated position holds your board firmly in place when you are taking care of your edges.
The one down side that I see about these is that it is mostly heavy plastic but as long as you take care of them they will take care of you and likely last the rest of your snowboarding life.
