I think you need to be realistic about what you are paying for and what you expect.
I knew this wouldn't be all-singing all-dancing due to the price.
I bought it as a starter / taster machine. I reckon if I use this for very simple projects, stick with it and do OK.
If I use this and want to aim to do more complex stuff then, I'll invest in a more expensive more professional machine.
It's good for a starter.
It doesn't move too fast.
It's simple to use.
It's easy to thread.
It's NOT heavyweight.
It's NOT super-dooper.
BUT, for what you pay for it, it's a simple, good starter machine.
Don;t expect too much.
If you want something that will tackle big jobs then, you'll have to pay for it.
For simple, easy, small jobs, this is good.
