It's a stable solution.

I would say the solution is stable because we don't use it every day. We only use it when we have a load test or when we have new versions of applications going out. The stability depends upon how the integration and setup are done. For every new release and every new change, a few things need to be tweaked but it is not something very complex.

We've had no issues with stability.

The solution is very stable.

We sometimes encounter stability issues, but they are not severe.

In my opinion, scaling the grid was easier to set-up than Jmeter, for example.
