This was mostly self- explanatory, but when I did have questions, Support answered them immediately with helpful, easy to understand answers and tips. All in all, so far, Zepto Product Personalizer is pretty darn good. I would recommend the app.
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.

Extremely useful app for customisation.
Atik from customer support helped me almost immediately with all the queries we had and helped to fix it from his end as well. Thanks man.
This app does a lot for the price. Does take some time to figure out and setup, but support is always there to help out and answer questions.
