    Great machine, does what it says on the tin, a lot sturdier than previous machines and faster too perfect for running up hems on curtains. Not the quiestest but certainly is heavy duty.

    It is a very good sewing machine - very similar to the old singer belonging to my mother. It is easy to use. I have only done one project so far and I am more than pleased with it. I can tell it is going to serve me well. I highly recommend it.

    I have found it very easy to use - great for beginnners - also the fact that the spool settings are pre-set at the factory is a bonus so no second guessing on first use.
