Actually great if all bags tightly would update 27/12/14

I bought the set to aufzubewaren the requirements for garden furniture. This works project.
Unfortunately, a bag, the air can not hold. I habs tried several times, but after one day, the vacuum was out again. So I could only use 2 bags. What a pity for such a practical product. Another set of this manufacturer had a defect.
The handling is easy and if the air is just to get out, you save a lot of space.
Because, unfortunately, some of the product does not work, from me it only 2 stars.

After I contacted the customer service of the trader, has helped me very quickly and easily with the defective bags.
I just received a credit for the defective bags.
Also, I got the set with the defective bag free again sent.
The dealers here and there even seems to be reckoned with defective bags, but makes up for it with exemplary Customer Service.

For this, I am willing to change my rating of 2 to 5 stars.
The product is really great and the perfect customer service.
