Vacuum Storage Bags (Variety 20 Pack)

Why did you pick this product vs others?: I have space saver brand bags that are between 2-5 years old that still work perfectly. The Ziploc option does not hold a candle to the original space saver bag. I just ordered a new set and was surprised that they feel extremely cheap, thin, and flimsy compared to the older bags I have that are still working perfectly. Even the sliding piece that is used to make the snap/zip  seal airtight is now a flimsy piece of plastic without the grooves that align with the seal. A couple of the bags in my recent order arrived with gashes/ holes that appear to be due to folds/creases and pressure, not some external mechanism. I will update on the quality of the vacuum seal with this thin plastic—another review reported that the thickness has been reduced from 0.9 mm to 0.4 mm. That is a significant change in quality from my assessment.  I wonder if there is a counterfeit version that Amazon is shipping by mistake?  I believe the fail point is around the vacuum seal port and the thinnness of the plastic bag around that circle. It does not appear to be strong enough to hold up to long term storage.
