Never thought I could say this about a Burton product, but these tuning vises definitely suck. So let me elaborate to be fair. At first glance they look strong, but in reality they are wobbly. You have to really press down on your board to make it adhere to the suction cups. Even if you spread them out to give your board stability they have a lot of lateral flex so you can never feel comfortable just scrapping off the wax and brushing the board down. When you finally finish waxing your board and you remove it, you find 4 black rubber disc marks on the board. Yes you can remove the marks with alcohol, but in the case of the Dominant with the leather top, you need to scrub it gently with a brush to get the marks off.
