Amazing app and even better customer support! I use it for my personalized phone case store, and every time I’ve needed help, their team has been incredibly responsive and helpful.

They reply very quickly, and if something can be fixed right away, they take care of it immediately. If it requires a little more time, they always follow up by email and make sure the issue gets resolved.

Every experience I’ve had with their support has been 10/10. I definitely recommend this app, especially if you sell personalized products!

The app is a little laggy, I'm finding that my image upload box is not aligned to what I originally set it to be and I would prefer for the image upload/text to be able to be moved around however, staff are very friendly/knowledgeable. Support is prompt and my problem is resolved quickly. Rakib is very helpful and friendly.

I've been using the app for years. The setup workflow is great and highly adaptable to my store's needs. The result is a smooth customer experience and high quality exports tailored to our backend needs. Customer support is quick and incredibly helpful with coding fixes on their end so the app responds even better to our specific needs.

Have used this app for years and am really happy with it. The customer support is great, we had a bug after updating the theme and it was literally fixed in minutes. Great customer support

This app has been great for us at Hamag. It allows very detailed personlisation along with the ability to show our customers what the customisation will look like. The support is second to none. Always ready to help out and very quick. Highly recommended.

Been using the app for a few years now, from the old legacy version through to the new version.
A few issues along the way, but nothing support couldn't help with, in a prompt manner!
Very handy app for us, managed to reduce our processing times considerably.

We have been using this app for about a year now and have had nothing but positive experiences with it. The support staff is also top notch. The level of detail they have provided in solving some limitations we have come across has been amazing.

Works well, good support. Would be nice if the issue with changing the image but not the name in an image set was fixed.

This app is CRAZY! There's just not one personalization can cannot be accomplished by this app. Sometimes the conditions can get a little tricky when you're not the most tech savy person but the SUPPORT, OMG. The team is AMAZING, they're available 24/7, they're patience, empathetic, so much value. They teach you, help you understand. 10/10, everything is outstanding!

This App often causes Various errors. Add on Fee sometimes dissapear, causing customers only paying basic fee even when they chose more expensive options.

Image Links often break randomly, causing error popups beeing shown to customers. Especially after there has need an update suddenly problems apear months later.

Customer Support is quick to reply but often just telling you what the issue is instead of helping you fix it. Get ready to talk to them for an hour and then redoing products every now and then. Quite annoying if you have complex Products

Hi Koni Design Shop team,

Thank you for 3+ years with us, and for taking the time to write this honestly. Reading it is hard, but it's the kind of feedback that drives our priorities — so let us address the point directly.

Why the add-on fees disappear. This is rooted in a real Shopify platform constraint: customizer pricing runs inside Shopify's Cart Transform Function, which has a hard 11 million-instruction compute limit and a 20 KB output cap per cart. On carts with many personalized items — especially when other installed apps (translation, bundles, currency converters) re-process the cart attributes — these limits get exceeded and Shopify silently falls back to the base product price. The customer pays less, and you don't see it until the order arrives. This is a known industry-wide issue affecting every app that uses Cart Transform, not unique to ours, but we own the responsibility of handling it well.
What we've shipped in the last month specifically to fix this:

Rewrote the entire pricing function in Rust — 20–30× faster than the previous JavaScript implementation. Carts that used to fail at 7–16 personalized items now safely handle 100+
Added auto-repair for cart lines where customizer metadata goes missing mid-session

Added an output-size budget check on the storefront — if a cart would exceed Shopify's 20 KB limit, the Add to Cart button is now disabled with a clear warning before the customer reaches checkout, so silent fallbacks can't happen

Our sincere apologies for the accumulated frustration. We want to earn the next 3 years.
