The ease of use is one thing I like best about this product. It's very easy to install in any device with an internet connection as well as being simple enough that anyone can learn how to utilize it without much trouble at all. If you are looking into VoIP solutions then there really isn't anything bad here other than maybe some lag times when talking through certain devices (especially cell phones). It does tend to have lags sometimes but overall not too many issues from my experience so far. We were searching around online trying to find loads balancers and found nothing we liked or trusted so decided to give it try out ourselves since we had previously used Skype before which was great until they stopped supporting their application due to changes by Microsoft.
