@Sara-S I have a Brother and I love the needle threader. The only problem I have with it is if I am using very fine needles, then the threader hook can miss the eye, but I don't stitch very fine fabrics much so not a big deal. I've had to straighten the hook once or twice but, with a good light, a magnifier and some tweezers it's easily fixed.
The variable speed button on the left of the control panel is really useful if you are doing buttonholes. For these I unplug the foot control and let the machine do its thing, but at a reduced speed so, if it snarls up for whatever reason, you can hit the stop button before it's had a chance to make a horrible mess. Doesn't happen often, fortunately, but on mine the machine gets it into its head to play up occasionally and needs to be spoken to sternly!
Also, after a few years of cursing the lack of facility, I found out purely by accident that when you are in the default straight stitch mode, it's possible to move the needle rightwards in small increments, presumably in your case using one or other of the +/- buttons top right.
My only warning about these machines is that you need to be really careful not to let bobbin thread get tangled around the bobbin winder spindle, else the winder may stop working and the machine has to be almost taken apart to get at the detritus, which is a pain.
