Query: More frustrating than useful

It jams frequently, making jobs take twice as long as they should. Sorry I bought it, especially since the return window is closed now. It's something we don't use that often, so it took more than 30 days to realize that the first bad time using it wasn't just a learning curve. By the second time we used it with the same frustrating results, it was about 40 days after purchase.
