When you are at an amateur level, use the trimmers for trimming only. You may want to use it for creating or trying out different styles but refrain from doing so because that is not the best option for you. It can easily go really wrong and spoil your style.
The trimmers should be with adjustable blades so that you have control over the length of your hair for a better trimming experience which is symmetric and consistent. Also, they should be light weight. It becomes really uncomfortable to hold up the trimmers for that long.
The trimmer should ideally be both electronic and battery operated because you would not want to be stumped half way through your hairstyle because battery died or electricity did. It is very important to finish the trimming overall at once.
