I can provide a review for one of the products that I have experience with. The kind of testing tools we use includes a real phone for testing our application, but we were searching for a cloud solution for testing. However, we ultimately did not choose any of the companies we were trying.
My experiences with BrowserStack and LambdaTest include conducting very important tests on both products. I was really surprised by LambdaTest. It was a very good service and for the price, I think it is a very good solution. However, we did not test all of the products, as we only tried these two products.
We tried LambdaTest for testing to determine if the solution could be a good fit for us. The testing was conducted during one month with 20 people for evaluation of the solution.
Geolocation testing helped verify localized content, as we used this function, but I did not test it very deeply, so I do not have comprehensive information that would be useful.
After a few months, we realized that the phone that we have was sufficient for us.
The main differences between the real phone and LambdaTest, in my opinion, are that because we have old iPhones, we can give the employees who need a real phone for testing a device. We were searching for a solution to help them access a different kind of iPhone. If I were the only one to decide if it is a good solution, I would choose LambdaTest. However, because of the many phones that we have, the final decision was to keep our real phone. I think in two or three years, we may need to reconsider this decision.
