What do you like best about the product?

We have a queue wrapped around our website at all times and appreciate the security this provides us should there be unexpected/expected surges of traffic to the website.
It has good reporting features and the customer service agents are very responsive and friendly.
We have also had positive feedback from customers that they enjoy being able to see what their place in the queue is, their expected wait time and have the option to receive an email when they reach the front of the queue.
The interface is quite simple, so easy to learn and the documentation provided is extensive.

What do you dislike about the product?

We have some negative customer feedback about being kicked out of the queue but we suspect this is due to them using multiple tabs/browsers/devices.
Some 'how-to' videos would be good for training as some staff members are visual learners.
We recently ran into an issue where Google could not index one of our pages because there were too many queue re-directs.

What problems is the product solving and how is that benefiting you?

Maintaining a queue on the website constantly to prevent overloading, especially during busy onsales where we can have upwards of 25k people queuing at once.
