Bests & Worsts Reviews from Amazon

Love the label maker but the labels aren't sticking -- I bought it to label holiday decorations plastic storage crates with contents and labels won't stick. I've put books on top of them, etc. Ended up putting scotch tape over the labels. Also tried it on glass mason jars again labels won't stick. I don't know if I got a bad cartridge and need to try a refill but totally defeats the purpose if I can't get the labels to stick!
