The device is not to be compared with the Billi devices. Absorbs most of the air and creates a stable weld. The handling is very simple. The tilt function is very convenient to store the unit. However, there are also a few drawbacks and therefore a downgrade The Origianlrollen are totally overpriced and the roles of other manufacturers often do not fit, because usually 30 cm width 28 cm will be offered instead. I eventually still appropriate roles of Gastroback found that including shipping costs, half of the original roles. I'll keep my old Billiggeraet to as freeze Gartenkraeuter, otherwise the bag will cost more than the content. Another drawback is the fact that vegetables and fruit and meat actually need to be previously frozen, otherwise water is sucked in and the welding is not working. For high-quality goods for freezing is the device optimally for wegem times quickly freeze a few groups or small things not necessarily recommended the Vorfrieren and the high cost.
