I have a similar one, but have been disappointed by the fact the packets don't reliably stay under (relative) vacuum :
- using either the provided roll of bag material or standard freeze bags, half of the packets made get some air inside, after some time (even when just lying in my freezer – no rough handling etc..).
- I don’t think it’s the heat sealing which is not good, but the bag material itself, which leaks after a while or is too weak.
Anybody with a good experience/know-how on this kind of vacuum sealing ?
Good advices are welcome...
