Once the initial search is done, I didn't realize I should select multiple products and click "compare". Once I saw this, I wanted to sort the products by reviews, features, something.
Once in feature rating mode, the picture was tiny and there was no description, so I wasn't sure what product I was rating the feature of.
After rating the feature and in comparison mode, again I'm not sure which product is which, so hard to make judgements. After making a series of judgements, I noticed that I often had to scroll down because of the large white space at the top of the page.
As I progressed and continued to judge features, I had no idea where I was in the process, or many more questions might be necessary before confidence in a selection was clear. Once everything was completed, it's clear which one you recommend based on my judgements, but I don't know why or which feature judgements had the most effect.
Finally, when I went to share my results and sign up on facebook so I could be a super A2O contributor, it kicked me back to the original A2O main page and it did not save the comparison I'd just done.
Good luck!
Thanks for the feedback, it's helpful to understand what should be improved overall to have a better method to match products to user preferences.
