      I've been using this for a couple of months now, and it's been fantastic. At first, I had a bit of uncertainty as to what settings to use for vacuum strength and sealing time; this boils down to a couple of simple things. For sealing time, the default is just fine for 3-mil bags (which are the standard thickness) and I've had no difficulties whatsoever. For vacuum strength, what matters is, simply, how "wet" the food is. As air pressure drops, so does boiling point. In fact, at the maximum amount of vacuum this creates, tap water will boil at room temperature. For that reason, if you're sealing stew, stock, or some other liquid, you'll want to back off on the pressure a bit or else the contents of the bag will literally boil over inside the chamber. (If this happens it's not the end of the world, it's just a bit of a mess to clean up. The inside of the chamber is one smooth piece of metal, so it can be cleaned.) Also, make sure you cool down liquids before sealing them, since the higher the temperature, the more pronounced this effect is.

      I've used this for a few months now. Works well. Immediately returned original to Breville for exchange ... This review is specifically because Breville's very good customer service.

      I bought this know it was coming from Amazon Warehouse. Description was Used-Very Good. I did not know that very good only means the unit LOOKS nice because it sure was not a "Refurbished" item as described.

      Wow. Just an incredible machine. Works with every type of bag I've tried, had to increase seal time to 6sec for mylar bags. Where has this technology been?

      Just started using this, and so far it seems to work.

      I researched to see if anything came close that was cheaper and never found a great option. I have no regrets. If you are sealing with liquids involved for Sous Vide cooking the Polyscience 300 is worth every penny

      Been using the VP-215 with oil pump for 12 years...inherited the PolySci 300 with airpump and thought I would try it out...nice looking instrument. In general, it works, but it does not come close to comparing to a professional oil pump vacuum sealer. Complaints (1) noise (2) vibration (3) long time to reach max vacuum (4) lid does not automatically pop-open so many times you forget and find the sealed item the next day....the biggest issues are noise, vibration and a long time to reach vacuum (like 45 sec vs 20 sec with an oil pump. Go with an oil pump. don't listen to the reviews that it is lots of maintenance. I've had mine for 12 years and change the oil about once per 2 years. Easy to change oil. I use the sealer daily and sous vide weekly. I use the sealer for instant pickles, marinades, compressing fruit like watermelon :-))), sealing bulk foods, cheese, etc., etc. Can't live without it but go with the oil pump!!!

      I love the machine HOWEVER it quit working within the first year of having it. The company sent a shipping label and it was returned. One month later I still do not have my machine back. They were unable to fix it and will be sending me a new one as soon as they get them back in stock. I have requested to know what went wrong with my machine so I can make sure that it does not happen again. No one at the company can tell me this. I'm hoping that the first machine had a defect that the replacement won't have. I'd hate to think that I spent close to $1000 for a machine that only lasts one year (home use not commercial).
