WORKS GREAT!! Vacuum seals food for longer / fresh storage. I have used this one for 1 year, and liked it so much I got a deluxe model of the same brand. Great for saving $$$$$$$$$$$$ by buying bulk foods. Over a year, I have found the savings really add up!! Can use rolls, or separate bags, which can be purchased at Canadian Tire or online, etc. (net cost is about $0.15/bag – pretty cheap when you are saving big $$ on fresh produce and bulk foods) Happy to demonstrate for you (if you are considering purchasing an online ENTRY LEVEL vacuum sealer, I recommend you DON’T – my friend is having problems with hers and is very disappointed) $45 (currently $150 at Cdn Tire) https://www.canadiantire.ca/en/pdp/foodsaver-compact-vacuum-sealer-black-0439586p.html
