The app is very good; it has many interesting features to increase the average customer checkout, and it's very customizable and intuitive.
I had an issue with my website when using the Monster Upsells app. The customized shopping cart wasn't displayed on the website. I contacted support, and they resolved it practically within a day. Highly recommended app.

It's a decent application but some sections of the Cart Drawer have very limited options to customise. There is no option to modify the width of the Cart Drawer. Support seems to be non-existent and therefore we may need to uninstall it. $36.99 for only 500 orders? Ouch.

ohhh nooo sorry to hear this! We try our hardest to answer within 5-10 minutes. Not one of our usual support happy reviews. 😅 Thanks for the feedback. As for cart width... our team can easily customize this for you.
As for pricing our value should easil exceed the cost within those 500 orders. We get a lot of customers ask why we are so cheap for what we do. Always appreciate the feedback though. If you would like to try Monster again.. please reach out to the support team and we would happily extend your trial to give it a go. :) Ty.

April 19, 2024

this entire app does not work
super hard to customize
my customers click add to cart and it takes them to the homepage
then the add to cart pops up
then when you try and click the terrible looking upsell
it doesnt even work
support isnt online during normal USA working hours

I heard great things about this platform but overall experience has been terrible. I get things happen with these apps but when you are not even available to respond during normal working hours? Thats insane.

DO NOT USE THIS APP!

Hi team 🥰 Our app has integrated seamlessly with 4000+ stores out of the box - However your specific theme is a rare one we have to work on manually. Looking through records - I see team responded to your message within 6 minutes. I'm sorry if you expected it to be faster. Support is sometimes working with multiple stores and gets to you as soon as possible. If you would give us a chance we'd love to help get your app up and running perfectly.

(Also.. just wanted to bring to your attention... your store may have recently been hacked. I can see a different site appear when clicking your URL. Hoping you can get it fixed soon and back selling) Ty 🙏🏻

I recently encountered some issues with the Monster App Cart, and I must say that Charlene provided me with outstanding customer service. Her dedication to resolving my problems went above and beyond my expectations.

Charlene was not only prompt in addressing my concerns but also demonstrated a deep understanding of the issues I faced. Her patience and willingness to guide me through the solution made the entire process much smoother. What impressed me the most was her genuine concern for customer satisfaction.
