Question: Years ago I purchased two (2) FoodSavers VAC550.  I have many VacLoc rolls and bags.  Can they be used with the new models?
Document: I've used Foodsavers on and off for probably 15 years now and I've gone through at least 4 of them. I use them infrequently, about once a month on average. My experience has been that after about a year or two of service they cease to function for one reason or another. I bought the V3835 about a year and half ago and have used it so infrequently that I have not even used all of the bags that were included when I bought the product.
I have owned many foodsavers over the last 15 years. They are great products that really do save you money. The 3835 and 3840 models leave a lot to be desired.Tilia needs to go back to the drawing board and take the "automatic" out of the machine. The entire sealing process takes at least 2-3 times more time to get the same job done.
I used the original Foodsaver for many years until it finally expired from exhaustion. Received one last Christmas and threw it away after two frustrating months. The new design is difficult to operate, functions poorly, is difficult to clean and generally is a waste of money.
Wow...I wish I had purchased one of these years ago. No more frost on the frozen meat, etc. Easy to use. My only negative is I wish the instructions were a little more clearer regarding the rolls and how to use, but I am able to make the size I need so guess that is okay!! Recommend highly! !
My wife and I received the V3840 as a wedding shower gift about 2 years ago. We love to buy meat on sale, vacuum seal it and freeze it. I'm not sure how much this actually saves us but I've never had to throw something away that I've vacuum sealed and froze. We've used the seal and steam bags which work great for vegetables. My wife likes how you can buy in bulk and portion out the food into small bags. You can re-seal foil and plastic potato chip bags.
I purchased the V3835 nearly two years ago online and still get frustrated every time I use it, which has been about 5 times. It is the most unpredictable, unreliable piece of equipment you would ever purchase to use in the kitchen, or where ever.For starters, sealing. Sometimes it will work first time, other times may take up to at least 10 pass/insert attempts. The vacuuming brings the same results happening all over again.
We've had 4 foodsavers over the last 10 years. They were always hard to deal with but they worked well. Decided to get this new one when the rubber seal on the old one started to go. The first one I got never worked. Called and Foodsaver couldn't have been nicer. They replaced the first one. BUT this model just doesn't work very well. Finicky and slow compared to the older models.If your old foodsaver is working don't even think about this model.
I had an earlier foodsaver which worked great for 20 years. It died recently, so looked to replace with the new model. I was concerned with all the negative reviews, and reported problems with the V3835. There were so many reported problems that I actually delayed purchasing it as it appeared to have significant issues. Finally, I could not live without a vacuum sealer, so I broke down and purchased it. I have been pleased, and have had no problems after six months of regular use.
I have been using one of the original FoodSaver Vacuum sealers for many years and it finally died. We purchased this new FoodSaver V3835 Vacuum Food Sealer with SmartSeal Technology and I am loving it! My wife likes the sleek design so much so that she will even allow this one to stay on the counter top in plain view (she's not an appliance on the counter type person). I like the one touch feature. No more having to hold the sealer closed till the sealing action is finished.
After filling the bag, getting the open end into the slot proved, again to be a challenge. After several tries, I finally got it to vac and seal. The motor that clamps the bag is loud. The vacuum pump doesn't seem any louder than on other models.I tried two different rolls and pre-cut bags, and the result was the same...frustration. The fuller the bag, the harder it was to get the end into the slot.
Answer: Yes! The hot "bar" where you fuse the two sides together is 12" wide/long, so as long as that part isn't any longer (the already-fused sides can be as long as you like, of course), it will fit just fine. I had an older model, & continued to use up "leftover" bags on the new. BTW - I get my bags in 4 or 5 rolls (differing widths) contained in one green box, from either Sam's Club &/or Costco; buying them in the box saves one quite a bit of the other green! �
