I think this is a brilliant product, it definitely feels to me that it fills a massive need, with reviews in their current state being extremely hard to quantify.
The Review Index definitely helps paint a narrative to all the reviews in a kind of unified review. Love it, and will continue to use it.
I have used the platform to compare the features and reviews while buying a mobile phone online. It's extremely convenient to have all the relevant information. It helped a lot while taking a buying decision.
