My Five stars are Mainly based on the awesome price and the quality of the bags which are the best ever vs the bargain price as it exactly does what its supposed to do - which is vacuum seal things, with no lose of seal.No air leakage.
Exactly what I needed, large enough to store spare duvet & pillows, they do come with a blue tab to help seal but this is not always needed. Easy to remove excess air through the vacuum vent & seal before air escapes.
these bags are great. better than more expensive ones. will definitely use these in future.6 vacuum storage bags 100 x 80 great bags. great price.
For the price you wont be sorry. The seals are good. Using them for big king size duvets, still sealed and tight over the time.
There bags more than three times the cost, which I can't imagine how they'd do better job.
Its normally not worth buying cheap and some time we can face problems , but this time You wont be sorry as this is the exception that proves the rule.
the last thing I want to add is to be sure to press and seal the zip-lock 2 sides very well ,using the provided zip lock tool and also your hand can do this.
