The solution is stable, but I've noticed some issues with the speed and overall performance. For example, when I'm using my development laptop, and I switch to LambdaTest, the performance decreases. This is especially noticeable when I'm using a dimension that is working on the laptop, and I try to use the browser. In general, the availability of the device could be improved.
Other than that, I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow.
My main concern is that the camera is not available when I'm using LambdaTest. However, I've been able to work around this issue by using the camera to check my connections.
Overall, I would rate the stability a seven out of ten.
