My previous Singer machine had automatic tension adjustment and this machine is all done manually. It was frustrating to me at first to get it adjusted properly but finally at #5, it sews like it should. The more I use it, the more I'm liking my machine. I had no problems adjusting to doing the bobbin a different way and I can tell that it has speed through different types of materials. I believe I did make a good choice and I'm sure that after a few months of regular use, I will say I love my machine.
