Too bad I could not give a better rating. As much as I'm willing.

Despite careful bonding overnight it has with me not once suck endured! There was a small hole of 3 cm. This I did, I noticed through the miserable suction. Since dirt on the bond was, it was no longer possible to renew this again. The bag thus lost its purpose. Basically, a good idea! But if a great pity! A return would not be worthwhile for me because me the expenses in relation to the costs appear uneconomical. However, would appreciate a response or consolation from the seller yet!
