TrustRadius - trustworthy reviews from real world users

We were looking to purchase large enterprise software such as customer relationship management, BI platform and business process management. I was part of the pre-project team, IT specialist, and I had to analyse what was available on each platform's market, in order to know which company should be contacted for more information. During my investigations, I found TrustRadius had very valuable reviews from other people. That made me [save] very valuable time and go straight to the best solutions/vendors

As for software pricing, I don't really rely on vendor information on TrustRadius because our purchase process always includes a negotiation step with a very tough dedicated team. During that step, vendors always include special offers and commercial tricks that make the pricing different from public pricing. I am interested in pricing information on TrustRadius though, in order to have an idea on what offers other users got.

In my opinion, G2 [is the] only comparison with TrustRadius. I even think that TrustRadius covers a wider range of software. The other sites I tried were either unfriendly to use or had bad quality, untrustworthy reviews. When I use TrustRadius, I know that reviews are provided by peers and counterparts, and not by vendors.

I sometimes use the Gartner Magic Quadrant. For me, it's useful if I want to have an idea on competitors at a glance. It may be helpful to quickly get a clear high-level view to discover vendors/outsiders I didn't know.
Gartner's Magic Quadrant is a helpful hint provider and may be handy in a presentation, but it doesn't have a major influence on purchase decisions.

I don't always purchase the product with the highest score. In fact, I don't take into account reviews that are too positive. A good product rating is the one that is consistent with the written review. [And a] good written review is the one that puts forward the pros and the cons of a product/software in a given usage (ideally the same as mine).

I didn't really face challenges when researching reviews on TrustRadius because it does exactly what I expect: help me narrow up the software list to the top 3, get real-life reviews and get an idea on hidden costs. After this step, we are used to directly contact vendors for POCs or further information. I think it would be challenging to make purchase decisions for software that have very few reviews.
