I wouldn't recommend it for translation **to** Esperanto. Experienced Esperanto speakers immediately smell the Googlish Esperanto when they read it as it's quality is quite poor.

I once received an email from a woman who wanted some sentence in Esperanto as a tattoo. She asked me if it's correct and and I thought: Smells like Google translate. 

Short: Don't use Google translate if it's not only for your personal understanding.
