It works well. Installed it several times before I figured out how to get it to work. I won't go into how to install it cause there's enough info here on Amazon in the reviews for anyone to be able to figure it out. The most important thing to remember is that they set the default IP Address as one that is very commonly used so many people will have conflicts with other devices during set-up like i did until I figured it out. I will just say that the biggest let down is that it is falsely advertised as having "bi-directional communication" when it does not truly have that feature. If it would've then I would've given it 5 stars and I would've kept it.
