DPO Dynamic Product Options

The app is very very easy to use.
And when you have questions and ask for support (did it twice now) support response within just a few hours

I wanted to wait until our shop went live before leaving a review. We only have 4 main products but each has between 150 and 650 variations -- we make them to order. Itoris Support went above and beyond expectations. From the initial set up, to helping with clear instructions on setting up all those variants, to helping with a hiccup or two once we launched. I would highly recommend this app. PLUS, one of the very few out there that will allow an option/variable to subtract from your "main" price.

This is a solid app. It includes so many features to customize your product pages with custom options/add ons, etc. very good support as well.

Of the many apps that I have searched for and tested, this is by FAR the most reliable. It simply has always out-performed any other for comparison. Our product can't be presented with complex options and so many permutations without this app. Good documentation, tutorial guidance, and efficiently designed code is an absolute must and Roman always comes thru!!! App provides a built-in conditional filter in presenting options that would make it easier for customers to select options. The support is great and Roman responds almost immediately which is amazing considering the time zone differences. His solutions are smart, concise, and bulletproof. I'm most grateful that I can trust his high ethical and work standards.

No other APP gets even remotely closed to this. Incredibly good and flexible. Support has always been very efficient too.

Great and mighty app. Great and insane support. DPO is an "almighty" app to realise a multi-multi-product-selector as we needed it. You can realise a lot of options. Thanks to the excellent support! We should have contacted the support much earlier!
One point to improve is the written documentation: Compared to the tons of possibilities of that app, the documentation lacks of a deeper view.

Love this app! We've tried several others and wish we'd found this one sooner. Easy to set up. Love how fast it loads. Roman's responsiveness and support with minor customization requests has been fantastic. Very happy!

Amazing app with great support. After evaluating most of the product options apps, I think DPO is the most comprehensive app out there for Shopify merchants. It is highly configurable and that also makes it little complex, thanks to excellent support from Roman we were able to get this configured exactly as per our requirements. Great job guys!

One of the best apps on Shopify! Easy to use with various functions to take care of all the requirements and exceptional customer service! Thank you for all your help!

Most powerful & well run Shopify app I've come across in 12 years of using Shopify. Full stop. Brilliant functionality and epic support from Roman. At first glance it takes a minute to digest everything that is possible and it can seem overwhelming - but - once you get your hands into everything it really is as powerful & reliable as you need it to be. I had a couple glitches come up and also needed a little custom functionality - I was able to get a reply, a fix & custom edits completed in about a 1-1.5 days per request max. Sometimes the replies were minutes apart. Im blown away. I'm paying for the max subscription and I feel it is worth every penny. Only suggestion for future improvement is more content available for self training for those who may not be as intuitive in understanding it - but the excellent customer support fills this gap in the interim.
