Yes, the build quality is good, and yes, it does its job well. However, there is something you should know before buying. I wish I knew. Other reviewers, very condescendingly, described the controls as "non-intuitive". To warn future buyers, I'll be blunt: the UI is a smoking heap. Hmm garbage. You get a three-digit display and two buttons, each with multiple functions. As others have pointed out, the design decision itself was stupidly stingy. A pen and another number (to indicate short words)
