Danbo ----a warning-----just threw out 3 cheeses that were vac packed and placed in my garage fridge----kinda forgot them----but the vac bags had leaked and were full of air, they were dried out moldy bricks. I have had some problems with this before----never figured out if it was bad bags or a bad seal----since then I have double sealed and that seems to have solved the problem----have talked to other people that had this problem, but it's not all that common.
Also-- the vac bag can leave impressions in your cheese----some people hate that.
Mal----I guarantee it works better then the old hand pump----had one of those for years-----but it can crush the hell out soft and semi hard cheese.
