Query: Poorly made

I have owned this machine for about two years now, and have had trouble with the tension and with uneven stitches since I purchased it. After taking it in to get serviced this year, I found the spool tension was designed too tight, making it difficult to accurately adjust the upper tension. It tends to work ok for half of a project and then knot up and jam. Sometimes changing the needle helps for a while, sometimes taking out the bobbin case and replacing it. Usually I just have to walk away and let it rest for a couple days. It's incredibly frustrating. The stitches have continued to be uneven and skip at times, too, even after the tune-up. The mechanic who worked on it said these newer machines with everything internal are harder to repair and often not made as well. He was as unimpressed with this machine as I am. I just wish I had realized it was something that couldn't be fixed before it was too late to return it.
