You can download the Glassdoors app and see all reviews for free; I've used it previously. Looking at Livetiles, you can see all reviews at no cost.
Be warned - anyone with an axe to grind, or an agenda, can pretend to be an employee. A couple of few-star reviews by current employees says to me that those reviewers either aren't a fIt for an Agile organisation (and would be toxic in the workplace), aren't real, or are genuinely dIsaffected and don't have the cajones to move. Which says somethIng about them.
