Great product. Too many browser extensions (or even one) can degrade the user experience but Primary is one that is worth having to get much more in-depth information and specific product feature knowledge to make better purchasing decisions. Relying on Amazon (or other e-commerce site) reviews no longer help given the sheer size. No matter the rating, you'll find many reviews that love and hate the products and everything in between rendering it pretty much useless in actually making a purchase decision. Primary takes you to much more informed discussions where users can actually give you detailed input on the trade-offs made on each product which is much more useful than "works great for me, fast delivery!". Can't wait to see the product evolve over time to surface the most relevant forums making it even faster and streamlining the daunting task of making expensive purchases over the internet.
