I tried a cheaper brand, but got a lot of failures. The cheap ones would seal ok, but would apparently wear a hole while in the freezer being knocked around. Then I would find the occasional bag unsealed and the food inside frost burned.

These Weston bags are heavier duty, and seem to hold up to getting jostled around in the freezer.

Wow I have to change my first review, which was fabulous. I could not understand people talking about these bags failing.... well..... now I know what people are talking about, I have an entire roll of this stuff and almost every bag I have made fails.... obviously there are some serious flaws in their manufacturing or who produces these for them.

After this painful experience and losing lots of meat to freezer burn over the last several months, I do not think I will buy these again. It is not worth the cost of steaks gone bad and having to redo bag after bag I find in the freezer that has failed. I threw this roll out.. $15 down the drain (had it too long to return to Amazon) and had to go to the store to buy some bags to save my meat.

Sometimes it works in my FoodSaver (V3230), sometimes it does not. Maybe the bubble-like side that my FoodSaver can't handle. Very frustrating to mark a prepared bag, insert the food (chicken, steak, doesn't matter) and than the FoodSaver doesn't vacuum the package. Tried cutting a new edge on the bag, then having to toss the bag and start a new one since the vacuum doesn't work on the food. Even walnuts were a problem. I prepackage them and vacuum seal them from a larger bag (32 oz. from Sam's). So if the vacuum doesn't work, it's not a problem. When I try to do pork chops, chicken parts, or steak, it is a major problem. I would not recommend these bags for the FoodSaver. This roll is fine for non-vacuumed items, but I will not attempt to use them for anything else. The price is good for the roll, but I don't feel the product works for what I bought it for. FoodSaver rolls are expensive and I use an alternative that is smooth and that works for me.

For a fraction of the cost of the store brand stuff, this is the perfect solution if you freeze a lot of meats. The tubes are too big to fit into self contained vacuum sealers, but if you save an empty tube from a previous roll, then you can re-roll half of this one onto it and it fits with room to spare. The quality of the material is comparable to name brand, and the The FoodSaver V3440 Vacuum Sealer has no issues with it.

Update 8.22.2016
I ran out and had to get the store brand in a pinch. Holy cow it's infuriating having to spend so much for so little. I have reordered this brand 3 times now and will continue to do so in the future.

Such a wonderful product and just the right size for single serving meats and fruits (pre-measure the fruit for muffins and seal, one less step on a busy morning). Do pre freeze fruit, it maintains their shape and juices. These bags seal with-out a problem, be sure to wipe the inside free of moisure at the opening of the bag if you don't prefreeze meats (we didn't prefreeze and discovered the juices from meats and fruits prevented sealing if the bag was not wiped dry). We will re-order this product again.
