Really good customer service, friendly and quick. The app is easy to use and professional, with lots of options for customisation so it blends well with my store. It does exactly what it says it does!

Monster Cart is very detailed, interactive and well laid out cart feature. We did notice it was a little slow at first. The customer service team were very quick to respond to our queries.

Great app & incredible customer service. Set up is super easy and there's plenty of videos that show you how to set up everything. Thank you!!

The Monster Cart Upsell is an excellent and highly useful tool that has provided me with a lot of convenience and great assistance. The technical team is also incredibly enthusiastic and has always offered me effective support whenever I needed it. I highly recommend it!

Really fast response! I had only added the app to a clients site and with in minutes they were helping me with a question I had and setting up a few things with me. Really great team!

Wow! The customer service is impeccable! I’m a newbie and the app is so easy and user friendly. I was stuck on one bit and spoke to Charlene who fixed it immediately. We are so happy with supporting them.

great experience with charlene very helpful and always goes an extra mile to help me with whatevers wrong, and gets things done quickly which is important for me as i run a lot of ads on facebook and cant have faults on my store. so shes a lifesaver! Thank!

In addition to increasing my AOV, Monster Cart goes above and beyond. At one point I thought I was having an issue with My cart and asked the team at Monster Cart to fix the issue. Not only did they figure out the issue was not with their cart but they also figured out what the issue was and how to fix it. The issue was with a totally different app but they put in the extra effort to ensure my shop was up and running correctly. Well done Monster Cart Team! V/R Reese It’s All Good Seasoning

Support has always been helpful when needing to make custom changes to the cart drawer. Great experience!

Love this app sooooo much. SUPER easy to use, and what I like most is if you need help, they are super helpful over email. 1000/10 will continue using this!! Thank you guys!

So far customer service is excellent. A representative immediately found an error in a change I was making. She alerted me to it and has developers ready to fix it. This was probably the fastest I have ever had someone help me on any part of my business. Thank you Angelica!

Charlene was 10/10 support she helped me so much as well as educated me on the features of the app!!!!

We've used Monster Cart Upsell for several years now and it works well. Their customer support is also very quick to respond. Their live chat isn't always available, but if you start a chat they will email you back pretty quick. I've also given them access to my online store several times and they're able to fix issues for me. 5/5 stars!

Great customer service and customizations on various cart types. I've been really happy with the adaptability of the carts/offers and have been able to easily tie the aesthetic in to match my store and product. Encountered some issues integrating with other high-level apps in store, but with the devs help we have been able to navigate through that as well. Thanks Monster Cart team :)

Solid app, great customer support. I found and reported a bug which the team promptly fixed within 48 hours.

Super easy to set up and use. I was able to message them on a Sunday and get the ball rolling to fix an issue.

We requested a refund because the app continued to run even though we believed it had been uninstalled. We haven’t received any response to our email. We generated 0 euros via this app.

That’s a wonderful app. I’ve seen other apps that are not as fast and are very heavy to run. This one is amazing, especially because of the kind of support they provide.

At BauUniverso™, we move fast — and so do they! I had a technical issue on my store that needed urgent attention. The MonsterApps team jumped in immediately, diagnosed the problem, and fixed it in just a few hours. Not only did they solve the main issue, but they also double-checked that all colors, sizes, and features were perfectly updated and running smoothly. Their communication was crystal clear, fast, and human — something you don’t often find in tech support. In an industry where delays are common, MonsterApps stands out for their speed, skill, and genuine care for their clients. They didn’t just meet expectations — they went beyond. Highly recommend them to anyone who values reliable, proactive, and high-quality support. Thanks again, MonsterApps — I’ll be recommending you every chance I get! — Founder & CEO — BauUniverso™

Charlene was very helpful and easy to chat with. Made my experience with Monster Cart seamless, highly recommend.
