I've been doing performance testing for, I would estimate, 10 or more years now.

I've been with the company for a little over two years. They were using it when I got here. They have used it for several years.

Four years.

I've been using this solution for three years. 

No issues encountered.

I've been using the solution for a year and a half.

Intensive use during 2004-2007. Some temporary consulting on 2012

One month evaluation task for a client that had specifically requested this tool for web, desktop, mobile automation. The client had used this for many years in his organisation and wanted to add more resources.

We've been using it for five years.

We've used it for three months.

Almost a year.
