This is not the greatest, but also not the worst. You have to figure out how to use it, which I have pretty much finally gotten down.
If anyone is having trouble getting it to suck/seal—is it running forever and never sealing? Even if it looks like most of the air is out?
Here’s the solution: you ABSOLUTELY need at least two inches of slack at the end you’re trying to seal. Also, make sure you’re on a large, level surface. Next, imagine there’s a tiny wall in front of those black guide notches for the bag, on the interior of the machine. Make the bag “go over” the imaginary wall, straight down in front of the black notches. Close the lid, making sure you press both the left and right sides down. It should work like charm.
