Oxygen causes iron to rust, fires to burn and fruits and vegetables to turn brown. Many harmful germs need it to multiply. Both oxidation and growing bacterial cultures spoil food. This process is slower when the air is extracted. Meat, sausage, fish and cheese keep much longer under vacuum than in fresh air; fruit and vegetables also stay fresh longer this way...

Very simple but functional vacuum cleaner without any major strengths or weaknesses. It is very compact and easy to operate. The spare seal included in the delivery is practical.

After a dozen uses, I am impressed with the device. The function is simple and easy to understand and the prices for the vacuum bags are OK. However, normal freezer bags cannot be used. Of course ? I can't make any statements about how it will behave after the 250th vacuuming. But the machine pulled a passable vacuum and the seams were tight.
