It works unlike others.
I have tried a few other big name chat systems. They where complicated to use, lacked the features that Zopim already had and did not allow initiate a chat. I few other had apps but they didnt work and was told by customer service that they where working on it. It never got fixed. I am impressed with Zopim product and the pricing is really reasonable. Thank you!
