It's great. Wish you didn't have to pay for more settings though. Love the easy functions of the app

Great when it functions. Has some odd bugs. Our settings will randomly revert from the custom css styling that was put in place. Also disabled on-page upsells will randomly enable themselves. Needs some work, but I like where it's headed.

I really like the simplicity and ease of setup with this app. I get the need to not be invasive with accessing customer data. But, the reporting can be improved by showing conversion rate info. It currently shows the cart adds, but not how many successful checkouts were made. It's next to impossible to tell if the upsell we create is working or should be tweaked if we can't see the conversion rate.

Hello. Thank you for your kind review. Yes, we would require access to customer carts and order data to show a conversion rate. The add to carts is an indicator and you can use your stores conversion rate to get a pretty good estimation. We will look to put add to carts on an individual upsell for a better indicator. :)
