They are both good and bad. It's good because electric models make your life easier. The timer helps you not to have to come back every time, and an electric Varmint guard (like electroshock, for example) helps you not to be bothered by other animals eating your potential prey's food. But as we mentioned before, the more details (especially electrical) you have, the higher the opportunity of breaking is. So, never neglect a guarantee. Actually, you should never do that.
