Great app for custom print shops! It offers advanced customization with lots of well-thought-out features. I've been searching for the perfect app for a while, and this was the first one to check all my boxes. The default design is fairly simple, but custom CSS gives you plenty of flexibility. Ramon has been very helpful and responds quickly.

Der Support ist MEGA und meine Kunden nehmen die App gut an.
Es gibt nur ein paar marginale Schönheitsfehler.
- Mobil ist die App etwas zu breit und muss manuell runter skaliert werden.
- Es können keine eigenen Kategorien mit vorhanden gemischt werden, was schade ist, da ich nicht alle Bilder übertragen, bzw. neu einladen möchte, dafür habe ich ja den höheren Tarif gewählt
- Ein umfärben von Elementen ist nicht nicht intuitiv möglich
- Die Bild-KI kann zur Zeit nicht wirklich viel und ist mobil schwer zu nutzen

This app covers all my personalization needs. Great support and feedback. It really has all the features I ask for regarding personalization. Sometimes I can’t believe it, but I’m proven wrong. Also, having translations available for all languages in the builder is just awesome. I really like it. there is a lot of documentation and support responds quite quickly—even in the morning, at night, and in the evening.

- There’s no bulk editing, for example, bulk delete or bulk select for all items.

This app cleared the frustration I had with other customizing apps, big time! It’s the best, and I’m not kidding. Don’t waste your time trying other customizing apps like I did. Ramon, who handles support for this app, can confirm that my page had plenty of them out of sheer frustration.
He went above and beyond, offering me special deals to support my business, coding the problems out of the way, helping at every step, and explaining everything with patience and care.
This app truly comforts me on every side.

The best personalising and customisation app I have found so far. I have tried several and they all have limitations that Qstomizer doesn't. Clean look, fast and supportive customer services, and offering many customisation options.

The app looks cool, but the setup is a bit confusing. My biggest issue is the lack of communication for help. I initially had trouble embedding the app into the site, so I sent an email for help. Right away, Ramon was responsive within the hour to help me get it fixed, which was great. But then I had some questions about certain settings and how to get certain templates set up to the way that I needed them, and no response after that. Over 24 hours later, still no response even after sending 2 follow up emails. The next day, I ended up submitting a new email through the "contact developer" link in the app store, and again received a fast response from Ramon saying that he'll reply off of my other email. I received his response, but it was unclear and also did not answer all of my questions, so I replied off of that email, but it has been over a week and a half and still no response in sight even with follow up emails. I don't have time to be ignored like this, so I'm ultimately moving on due to lack of response for support.

***Adding additional information after developer's response:
Developer is claiming that they offer a smooth experience and committed to answering customers as soon as possible. But when I ask a question and over a week goes by with no response, I highly doubt that is a fast response, especially when there is NO RESPONSE AT ALL. After sending a couple follow ups asking to please respond to my email because I'm still confused and I still do not get any response AT ALL, that is still hardly answering my question. I literally had to send another inquiry through the Shopify page instead of the email chain we were originally communicating from to ask to please answer my question and all I got from that inquiry was a "we'll respond to your other email in a moment" and then I received a response from the other email saying "I'm responding to your email now" and they didn't even answer all of my questions that were in there. I wasn't just asking "can I do this or do that" and what features the app does, I was confused and truly didn't understand even after watching the tutorials MULTIPLE TIMES. So I had more questions because I truly didn't understand, but yet I was left disregarded. But ok... chalk me up as a general merchant that doesn't like to check the tutorials. That's far from the truth. I'm the type of person that tries so hard to figure things out on my own so that I don't have to ask for help. If I'm asking for help, it's because I truly need it because I am unable to figure it out on my own. I seriously cannot get over the response from this developer. Had you reached out to apologize and continued to help me, that would have been such an easy fix, but you're trying to play victim (which you're clearly not) instead.

Exceptional Support from Ramon M. Ortigosa and Outstanding App!

I recently integrated the Qstomizer app into our Shopify store and encountered a minor issue where our website's header was obstructing the app interface on mobile devices. I reached out to the support team, and Ramon M. Ortigosa was incredibly prompt and professional in assisting me.

Ramon responded quickly and not only resolved the header issue remotely but also adjusted our chat button for optimal placement. He even provided a helpful tutorial on linking product variants with the app's templates, which made the process seamless.

His dedication to ensuring everything worked perfectly exceeded my expectations, his support made me signup for the full package right away. I highly recommend Qstomizer for its robust features and top-notch customer service. It's rare to find such commitment to customer satisfaction. Five stars all the way!

Qstomizer is the only app I have found that has the flexibility to accommodate the level of customization that we require. Ramon is very fast to help with any issues that may arise. We've been using Qstomizer for years and have been very happy.

The app is good and the customer service is fine.
The product is good but we can't put 5 stars because, according to us, some features are missing such as pricing ( Unable to price different images and clip arts - can't make categories with different prices - we cannot use this app as is).

I am thrilled with the Product Designer app! It's user-friendly and efficient, making the design process a breeze. The range of tools allows for my customers to easily create designs to sell on a range of our products.

The customer service is outstanding – responsive, helpful, and genuinely invested in ensuring a positive experience. Any questions or issues are promptly addressed, showcasing a commitment to customer satisfaction.

Moreover, I've noticed a significant boost in sales since implementing the app. The seamless integration into the sales process has made a substantial impact, and the personalized touch it adds to each product has resonated well with my customers.

Highly recommend this app for anyone looking to enhance their clients design capabilities, receive top-notch service, and drive sales growth!
