Review on 🛍️ ZWILLING Fresh & Save 30-piece Vacuum Sealer Bag for Food, 1/2 Gallon Size, Sous Vide Bag, Reusable Food Storage Bag for Meal Prep, Reusable Snack Bags, Dishwasher & Microwave Safe, Small, Clear by Ayoo Guzman

The quality of the pump, glass containers (including the lid), the thickness of the bags and the non-return valve on the bags are first class,, ,, excellent German engineering and Chinese Quality assembly,,,,, the zipper part in the "CURRENT" bags is a different story,,,, after sealing they seem to hold the seal but in most cases they don't seal 80% of the time first try and I suspect the sealing ability will diminish with each use. The reason I say "ACTUAL" bags is that the bags currently on sale are different than the bags pictured. I suspect the bags pictured were more expensive to manufacture and the zip part - the zipper has been redesigned to be more economical,,,, the bags pictured are (I think) made of a different material, which is very noticeable because the bags pictured have black zippers , the current bag zippers are transparent and the zippers appear to be made of the same material as the rest of the bag. Overall I like the product and will continue to use it but I plan to try what a few other reviewers have done and buy some cheaper bags from other manufacturers, groceries. Saver seems to be the most sold brand and if Gemini sees a drop in sales of their bags, they may decide that the new, cheaper bags weren't the best business solution for them and go back to their original design. A great product, which suffers from an easily fixable "vulnerability". The company's view of its customers becomes obvious when they just change the image of the bags. Do you list twin?
