TLDR: Positive experience, positive review. (compatibility heavy).

BrowserStack is our tool of choice for all our compatibility testing. Our team uses it as part of our verification process and has even recommended its use to our clients for continuity. We do our mobile application testing on App live and our web application testing on Live. The devices and OS are always up to date, and feature use/access is fairly straightforward. Looking forward to exploring this tool further as we evolve our test process and use different parameters. We recently added a beta feature to one of our accounts after a representative's recommendation and are happy to say it was easy to implement and allowed us to successfully continue our testing with little delay. Their customer service is relatively timely, often engaging in issue-resolving dialogue within hours of initial contact. I hope to see more integrations with their products and other distribution software; we recently switched to Bitrise, which is not directly unavailable via App Live (it is available on their automated tools), like App Center. Overall our test team is satisfied with the products we've chosen, and this tool has become integrated into our test process. Special thanks to the representatives for answering our inquiries and offering straightforward solutions!

Overall our project teams feel are releases have become more secure.
