So far, not only is this app incredibly helpful, well designed, and easy to use, but support from Clément has been the fastest of any app we've installed to this point. If your business relies on a persistent cart, this is the app for you.

I highly recommend the app. It also has great support, Clément is very quick to answer our questions, help us, consider suggestions for the roadmap, and implement them. We are very pleased with Casper.

This app is the perfect solution for our customers who are placing large orders and spending several days building their cart over multiple devices. I had a few questions and Clément was very helpful and responsive in addressing those. Thank you!

The app works really good! We suffered an incovenience and the customer support solve that really quickly! improving also their application. We are really happy that we can offer a better experience for our customers.

App is working well - I had a little hiccup but I reached out to customer service and they replied in under a day, and were able to help out. Very friendly service- Definitely recommend.

This app is a game-changer - well-priced, incredibly effective, and solves a major shortcoming in Shopify’s native functionality. Since implementing it, we've seen a significant boost in customer satisfaction. Clément is highly responsive and has even implemented new features based on our feedback. Couldn't recommend it more - truly a 10/10 experience!

Pooff just like that, carts were disappearing. Can you imagine Shopify tokenizes carts and doesn’t sync them across accounts? I know it’s hard to believe. In comes Casper, and without any issues, it just works. Carts are now synced effortlessly between devices for our logged in users. Definitely recommend.

Nice app, working as expected. Plus, we received quick and helpful support when dealing with a problem specific to used theme (Trade theme). Thanks Clément, nice work

I had an issue and I received a fast and good answer, even a follow-up of the situation till they solve it. Thanks Clement

A simple yet effective app for a very much needed feature that Shopify lacks, and keeps belittling as of today. Clément offered outstanding support and event took our feedback to improve the app, something bigger App developers usually don't do. A must have for any store in my opinion, from small to Plus ones.

Very easy to install and use. Of all the apps that claim to do this function, we found Casper to be the best. Easy to contact the developer directly with questions.

Such a simple solution to such a silly Shopify limitation. Incredibly easy to install and get going. Carts are now syncing across multiple devices, including items with line item properties.

The app works perfectly for synchronizing your cart on multiple devices. I highly recommend this app for this purpose! Thank you Clément for your outstanding customer support too, much appreciated!

Works really well with our custom theme. The only thing is, cart line item properties don't get carried over across devices
