Be careful (but this is a remark that applies to all adjustable frames) can not be used with a device (a paste) too liquid, otherwise it leaks from underneath. Indeed the adjustment system that the bottom of the frame is not glued to the support, there is a little light.
If you have a background that works normally. I used it for a cheesecake with a shortbread biscuit base crumbled, there was no leak. I think with a Genoese it works too.
