The PolyScience 300 chamber vacuum sealer has an average consumer rating of 4.6 out of 5 stars on most third party websites. Unfortunately, I could only find a total of six customer reviews. However, all of the reviews seemed to praise the same things: the external vacuum port and the pre-programmed commands.
Here’s a particularly interesting comment by Rebecca from Houston, TX:
“I love the pre-programmed buttons. There’s Maximum Seal, Medium Seal, and Infusions/Marinade (This last one doesn’t seal). I use it more than I thought I would.”
The pre-programmed commands are convenient and time efficient. It makes sealing and preserving your foods and precious items a stress-free, one-touch process.
VK from Ames, IA mentions the benefits of using the external vacuum port for pickling and storing fruits and veggies. VK said:
“My vacuum sealer helps me store and conserve raspberries from my garden. I just freeze them overnight, then slip them into a vacuum bag and seal it. When I’m done, I have about 3 or 4 bags of raspberries that are still fresh and juicy. Sometimes I use the external vacuum port to seal dozens at a time. It can take a few minutes to finish, but I just walk away and come back when it’s done.”
Common complaints about the PolyScience 300 Chamber vacuum sealer tend to revolve around its weight and size. At 55.5 pounds, this chamber vacuum sealer is both heavy and bulky. It does take up quite a bit of surface space in your kitchen.
However, its large casing and thick build supports its durability, while the sleek, stainless steel casing can complement any surrounding.
