I've been sewing for over 25 years and this is so far my longest lasting tool that I utilize often. When doing alterations, the long hand helps prevent fatigue and therefore you are less likely to hurt yourself or the garment.  For smaller stitches, it can sometimes be a challenge, but it is easily overcome by a little patience and by taking it apart from the right side of the garment. I recommend always seam ripping in good light to avoid eye strain and putting on relaxing music or the television so you don't grow impatient and rip the cloth.
