This bindings looks awesome on your board, but is a bit weak. I can't tell if this happens a lot, but the buckle on the lower strap got loose and fell off of the tip. Had to return it right away, and I don't think I would get these ever again. The way the buckle is connected to the strap just looks weak and it could snap anytime while riding.
Plus, since it's the cheapest EST, it doesn't come with the stance angle meter, just a cheap angle indication around the rubber of the base. Just check out the pics on burton.com and you'll see what i mean. Lame.
Spend a few extra bucks on the cartel est, or just get regular bindings.
