Back when I worked in a grocery store I received the Ziploc Vacuum Starter Kit for free. If something is free why not give it a try!? It actually has a really good concept and I was hopeful that it would work as advertised. I got the product, the bags and the vacuum pump thing and followed the instructions as directed. You could tell the vacuum was low quality, it was flimsy. The Ziploc bags were sturdy like usual. You basically just put the vacuum to the vacuum hole on the bag and got the air out. Everything seemed okay, not great but eh. Few days later I noticed the bags I vacuumed in the freezer not vacuum sealed. I redid it a few times. They just wouldn't stay sealed when I put the bags of food in the freezer. It never worked. I just tossed the cheap vacuum part and used the rest of the bags like usual. I don't recommend the product. The vacuum is such low quality. It doesn't do that much and then the bags only stay sealed for a brief period of time.
