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.

When I fist emailed the team asking them about pricing I got an email pretty quick, I emailed back to confirm a few things but did not get a response which was disappointing. In the end I decided to just try it anyway. So far so good, It was a little funny to set up. Overall though I just had to make sure I was going step my step. I had some issues with how the shipping slider looked and I was able to get some help on this which was great so I really appreciated that quick turn around. I have not seen any amazing conversations or increase as yet in AOV however, I am quite a new store and also I have only one campaign being used so these might be playing into that. I will see how I go and use some other campaigns and see if this helps with my conversions/AOV ect. would recommend trying it out and just seeing if it right for you.

The customer service is fast and friendly! The dev team have been great at helping make tweaks to the design of the cart draw to help match my theme better and have completed the work almost instantly. For this I am super impressed. I have tried a few similar apps and Monster is the best for conversion. I have come back to them after trialling others. I tried others because the aesthetic customisation wasn't enough for what I needed but after coming back to monster, the dev team have helped better this time with all the changes I have needed for the cart to match my theme. Last time they said it couldn't be done but this time they have completed with no issues. I would love for some of the design tweaks to be built into the app but it isn't a big effort to give the instructions to customer service to pass on to the dev team. I have also has a lot of requests for them and they have done a great job completing them all. Overall this app is amazing and has definitely helped improve conversion and upsells. I will never delete it again now!

Hi team.. thanks for the review! 🥰
Wish we could solve every single design change imaginable! We have designed with this in mind. However sometimes.. it's a little tricky to solve some requests. - Thanks for the feedback. We will take it on board :)

We used Monster Cart to add a 'free gift' campaign to our cart during the fathers day selling period which is our busiest time. We used a spend goal to achieve the free gift in the hopes that this would help lift our average order value. It has worked a treat so far. The how to videos were a great help when setting up all the features and although we had some small hiccups in the beginning the team were super responsive and solved any issues. Highly recommend

A very helpful app. Having the cart accessible at all times makes UX so much better. I also like the upsell and free gift capabilities. There are still some improvements to be had but I have been told it's all coming. Support is fantastic, with someone jumping onto the chat straight away, and going above and beyond to help me. Very friendly staff.

I use this app to offer gifts and incentives to customers. The extension works like a charm and support is great.

Great app. A few bugs here and there but nothing that their team can't handle. Makes it very easy to promote products and increase average cart value. Definitely worth the cost.
