I have now since about 4 weeks this vacuum sealer and am perfectly happy with it. The processing of the device is properly and Vakuumierergebnis as it should be. The double weld the bags remain absolutely tight.
Here, when the volume of the device is faulted during Vakuumiervorganges so I can not quite understand that. Surely it is so that the device performs its work not quite noiseless. But from personal experience I know that even the devices daszwei- to three times the VC100 costs are not much quieter.
Vacuum sealing easy "pushable" goods, such as bread or fruit, however, requires a little practice to get the right time to find for welding.
