I did loooots of research to find intuitive, easy applications to use for my upsells. I can tell that Axe Upsell Checkbox was by far the easiest and quickest app to implement that I have found ! It has already great custom options / tools, without being overwhelming which I find is super rare for all these apps ! The support is also super super fast and efficient. They will absolutely help you until you find the right solution. Thank you !!!

It is very easy to use and backed by excellent customer service. I needed a minor feature adjustment to fit my needs, and the developer responded immediately via chat and updated it.

the app itself is amazing. But I want to talk about the support which is in my opinion the most important. It is by far the best and fastest I've experienced with any app on here. They respond fast and immediately start to work on any issue you may have. Thank you!

Perfect app for upsells! Easy setup, fast support, works great. Really helps boost sales with simple checkboxes.

This app offers a unique upsell strategy I haven’t seen in other apps. It’s easy to use, well-designed, and doesn’t compete with traditional upsell tools—it complements them. Plus, the team is incredibly responsive to feature requests. Highly recommend!

Doubles user's cart. Settings of the app are not intuitive. I am a developer so it means for other users it can be more frustrating. For example the upsell adds to cart every time user visits a product page, which called a feature, not a bug. And you should know about it being present and disable it to not mess the user's cart Other thing which is why I removed the app from my store is it doubles the cart. I mean product A is on the website. Product B is upsell. User taps add to cart and 2pcs of product A are added to the cart. Product B is added also, which is expected, but not 2 pcs of A. Happens often. Overall bad app

Fantastic app, exactly what we need and Ralph was unbelievably helpful (and quick) in updating a feature for us so we could use it for our needs. Couldn't recommend more. 5*

Muy buena aplicación, tenia una duda y el soporte me respondió al instante, gran trabajo al crear esta app

great support from Ralph. Awesome and affordable app to use. I use it to upsell an extended warranty

Very bad speed optimization—a simple block with a checkbox, image, and title requires 3 CSS files. Also, one of them is font awesome, which is HUGE. A lot of people use your app, so you should optimize it before launching.
