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. — The Zepto Product Personalizer Team
After upgrading to a paid plan, you get access to live-chat support—and it’s stellar. The team is quick, friendly and genuinely committed to solving any issue. What holds the app back are the tight plan limits. On the €14 tier you’re capped at just 10 product bundles or 10 related-product blocks, which barely scratches the surface for a larger catalogue. Jumping to the unlimited plan costs around €90, a steep lift for young brands. I don’t recall the limits being this strict when I first installed the app, so that change feels disappointing. That said, the mega-menu and several other features work beautifully, so overall I’d give it 3 / 5 stars—great support and solid tools, but restrictive pricing.
I just got this app and am working through it but Jasmine and Anivia were trying their best to help me install and match it perfectly! I love that there is a verified badge but if you have old reviews from another app you will be out of luck as getting a verified badge on imported reviews wont be possible. Other than that i like it very much so far
