We originally had a huge license where every member of our team had a sign-in for the tool, but found that was overkill.  We don't use anywhere near the number of minutes we were paying for, so we scaled it back to one ID for the person who does the testing.  I'd say start small and expand if you find you need it; it will certainly vary depending on your needs.

One problem we've had is the annual license.  We have to have our team's assistant do the license on the company card, and then the company emails me addressing me by her name.  Sometimes it's difficult to straighten it out.  Since CBT deals with companies as its primary user base, I should think it would be easier to handle the annual renewal.

It isn't very pricey and it always has a great support system available.

SmartBear offers bundles of products that work together. If you find yourself utilizing other project management programs in addition to testing programs such as this, it is helpful to have programs that work together cohesively. 

The lowest price point is very reasonable. It is also useful if only one person in the company needs to check on the browser display.

The cost of this solution depends on size and demand.

It is worth the pricing as the product is supported on multiple platforms and browsers.

Buying a license is cheaper than procurement of in house devices and there is no maintenance cost either.
