Unbelievable customer support. I was using collections to support another app, and had created several that I did not want to show up in the compare drop-downs. I contacted support and they added a filtering feature for me in *2 days!* Outstanding.

Their support team is great! They go above and beyond to help fix issues that aren't related to the app. Five stars all the way!!!!

Giving this app 5 stars and will ask Shopify to support giving 6 stars when the developer implements some additonial features I have suggested. :-)

I looked pretty closely at all of the available product comparison apps and this one is the best of the bunch. There is a good amount of customization available, like where to place the compare button and the terminology used. You can switch on/off various standard fields you want to show/hide. Through its support of metafields, you can create as many custom comparison fields as you please. We use 17 as of now and few of the built-ins. Some of the other apps attempted to create a UI for managing fields, etc. I found them to be more cumbersome than useful. Instead, I just use Excelify: Bulk Import Export Update Migrate app to manage the metafields. It is a MUST HAVE if you want to use this app with metafield data, IMHO. I also like how it shows a progress indicator as it renders the page. I don't recall the other app that did not do that - I could see a visitor bolting thinking the page froze. So kudos on the UI feature.

Support was receptive to my suggestions. I really hope to see the ability to use the metafield namespace as a section header to subdivide compared product attributes. Support was also great in getting it to work in my theme, as there was a small issue. At $5/mo it is also a great value.

In short, when you compare the comparison apps Product Compare is beyond comparison. ;-)
