Firstly a correction. The sealer bar is 10 inches NOT 22 INCHES.This is important because of bag sizes are critical. You could benefit from my mistakes, and save money from day one by buying a single size bag at a fraction of the prices charged by the 'specialist' vacuum bag makers. These are available from a host of packaging companies. The cost of 1000 bags is around £40 whereas you will pay this for a couple of hundred max from the 'specialists'Any food quality bag that measures 200mm (open end) by 250 or even 300mm is the OPTIMUM size to go for.Smaller sizes than this have severe limitations when placing thicker items inside, because the opening gets smaller as you open the bag more.This size will take steaks, burgers, filets of fish and importantly (to me) a full spread container (we use old Clover containers) of either home cooked Spaghetti Bol, Stews, or anything else. A label with description and date in the bag is easily visible when the bag collapses around the contents. (not the spread container obviously) I use the container to freeze initially, and then transfer the contents into the vacuum bag.Much cheaper sealers are available but they do not compare to CHAMBER sealers. This machine is not a kitchen surface device. Think a microwave for size and weight comparison. If you have a utility, or even a table/ bench space in the garage, it is ideal. I researched and pondered for months, and i am delighted with this bit of kit!!Not in daily use, but if you want....Take away leftovers, or a full menu of home cooked food stored for up to a year or more from the freezer.....look no further.
