PMPMG reviewedLambdaTest AutomationAutomate cross browser testing with an online selenium grid
 RecommendedPros: 

- Automated tests with Selenium integration - Tons of browser + OS combinations - Excellent customer support - Nice UI looks professional

Cons: 

Screenshots results are neatly sorted by browser/OS. When you revisit report, layout differs and sorting is gone which is a pain.

I did a lot of research before selecting a tool for cross-browser testing. I chose LambdaTest and all I can say is: Great tool! I've been using it for a month and it has helped our agency eliminate extra computers, people and tons of time during our testing process and given us a wider range of possibilities.

PMPMG has used this product for one month.
