I have only recently installed this app, so it's a bit early to comment on the performance, but it looks great so far. However, I can comment on the customer service I have received since installing the app. I had a bit of a nightmare getting everything set up and looking how I wanted it to on my site, as I'm not the most technically gifted person, but Mimmi's customer service has been second to none! Extremely efficient and makes sure everything is exactly how you want it to be. Mimmi has really gone above and beyond for my business, so for that, a 5* is fully deserved!

I just installed it, and looks great on my site. Had a little trouble installing it, but it's just because I'm a rookie and didn't want to read through the instructions lol. Need to add TWO APPS: "Klarna On-Site Messaging" (this is just the placement and creative) which you can find in the Shopify App Store, and "Klarna Payments" (actual plug-in on your Cart page to enable the service) which will be sent to you from Klarna because it's not a public app (or something like that). Anyway, their support team was super helpful and walked me through the process. I recommend using them! As I said, I haven't had any payments via Klarna yet because I just added it a couple hours ago, but looks great!! Hoping to get some additional sales this way :) Thanks, Klarna Team!

There was a conflict with my theme so placements didn’t work but Klarna helped put it right very quickly. Special thanks to Mimmi who went over and above on more than one occasion. Lots of report Klarna helps AOV so I’m glad it was sorted. Defo recommend the service.

Installed the app but had some issues viewing the messaging on the front end. The support staff were extremely helpful and responsive, addressing my issue almost immediately.
Having Klarna on site has provided our customers with a spread payment option during these hard financial times.
