[EX Q]: For hours I have tried to figure out this machine. It finally got the best of me. It is being returned. I can't figure out how to bind 8 1/2 x 11 size paper. It leaves a half punched hole either at the top or the bottom of the paper and the combs they give you are too long for this size paper as well.
[EX A]: negative

[EX Q]: Don’t bother. I ordered the 10 pack of boxes. And what I got was seven boxes. 10 box lids. And three factory defect of boxes that can’t be saved they are glued backwards and attached at the sides. I worked too hard for my money to spend it on inferior product, I would give negative stars if possible
[EX A]: negative

[EX Q]: Wow. Quality control shipped is horrible. They shipped me a bike with a huge hole in the tire. Will never buy a bike off amazon again. This was a birthday present and i don’t have time to return the bike and get a new one for the birthday. So now I’m buying a new tire and inner tube. Will never buy a bike here again.
[EX A]:
negative
