Muy buena y funcional

This was a real easy, out-of-the-box set-up and use device. It works as expected and the only reason it didn't get 5 stars is: in order to hear the other side, the volume level inside with the microphones and speaker close together, (only separated by glass,) there tends to be a slight buzzing sound. Not overly bad and I may be nit-picking for perfection but this is an honest review and if I needed a second one, I would buy this same model again because it works well.

Microphone works great. Outdoor speaker is hard to hear on loud environments.

Great product.. very effective
