If a new product becomes more capable and has a competitive price, then it is possible we might switch to a new brand. We would do demos and validation to see the functionality along with all types of evaluations before buying a product.

We evaluate all the vendors every time because the capital equipment expenditure is expensive. So every two or three years, when we upgrade hardware, we go back and evaluate all the vendors, then decide what is the best solution. 

It is about who has a meaningful price, the right level of features that we need, and can provide the support that we need.

We always get equipment in for an evaluation. Usually a month is sufficient for us to run all our evaluations.
