This uses specially designed zip-lock bags. One side is sealed with a zip-lock closure, but the vacuum is achieved by puncturing a side of the bag and then heat-sealing the circular puncture that's created. The bags are meant to be reusable, but because the puncture-and-seal holes are in the middle of the bag, any food debris that's not completely cleaned off of the seal area will compromise the seal. When you reuse, you'll need to pick a new part of the bag to puncture and seal, which creates pockets between the holes where food tends to get stuck.
Also, the mechanical zip-lock closure won't hold a vacuum as well as a heat-seal all around will.
You can get a heat-sealing vacuum packer with a more conventional strip-style sealer for less than $100. You also need to buy bags for these obviously, but they are cheaper.
edit: Was mistaken that the seal was adhesive, as in the Zip-lock vacuum line. Thanks to Mark below for pointing it out. I don't feel quite as negatively about it, but still think conventional vacuums are a better option.

mozymokI'm not sure what you're referring to, the Oliso Pro-1000 is a heat-sealed vacuum packer, not a manual valve system.

MarkThanks Mark, you're right - I took another look at a friend's unit and it is indeed a heat-sealed hole where the vacuum is performed. This has its own problems, but it's better than the Ziplock brand design.

mozymokSo we've taken a look at the strip sealers as well. You sacrifice counter space because of the larger footprint. Also, with a strip sealer, you are always cutting off the top of the seal making your bag smaller and smaller after each reuse. Oliso solves those two issues.

andystrip sealers tend to have rather cheap refills as well, not to mention you can cut the bags to size and use most brands of bags Oliso bags are $15USD for 14 x 1 gallon bags, I pay $15AUD for two 5 meter x 28cm wide rolls of bags I couldn't find dimensions, but let's assume the gallon Oliso bags are 30cm long, that's $15 for about 4 meters worth of bags, less than half of a bag roll that I buy for my strip sealer Oliso bags are also not infinitely reusable, they say 12 times for the gallon bags TBH, I don't store my sealer on a counter (it goes in a cupboard when I'm done, so therefore that's a non issue I'm not saying it's a bad product, I'm sure it's a rather well made sealer But the positives brought up about it aren't really positives at all...

mozymokWould you mind elaborating on the issues you have with the Zip Lock vacuum pump bag system? I just started sous vide cooking and was planning to use the zip lock vacuum bags to keep my costs down but still get the benefits of the vacuum. Would I be better off with ordinary zip lock bags or this system?

SkanosThe Zip Lock vacuum bag pump will be fine for sous vide as you don't need the seal to hold for that long. You'll only start to see the effects of the inferior seal after several days. For food safety reasons, you probably won't want to reuse your bags, though. This makes using either of these systems relatively expensive. 20 quart bags will run you roughly $15 with the Olison system. That's pretty ridiculous, considering you can get a 1000ct box of regular vacuum pouches for $35.

andyA 20 count box of Oliso quart bags is $15 on Amazon. A 1000 count box of generic 6x8 vacuum pouches is $35. You don't need to bother reusing strip-style bags when they're that cheap.
Additionally, reusing bags that have had raw meat stored in them should be avoided, if that's the use case.
The counter space aspect is reasonable - the Oliso Pro-1000 occupies roughly half the space of the more compact strip-style sealers.
