Dealt with a few different operators (Mitali, Hamza & Danna) and all were very helpful with upgrading and transferring me from SC Products to Key Products. Instructions on email were very clear, and they did most of the work for me which was very helpful as I wasn't the original creator of our website! Thank you!!

Support is super and very quick. Got speaking quickly to a real person and they help me sort out a couple of issues I had. App is working well now

— Olivia's Haven

The customer service team has been extremely helpful with the transition from SC Product Options to Keystone Product Options.

— Four Brothers

Had some issues with product options not linking, and without any warning signals to say so, was going on for an unknown period. However the guys were fairly swift to rectify the issue, and also gave us a refund which is always appreciated.

— Fat Chimp Forces Wear & Gifts

Great app & exceptional customer service.

— Broadway Trophies & Engraving

Support has been very active in addressing migration concerns when we transitioned to this app from SC Product Options. It is a lot cleaner, responsive, and optimized compared to the previous app which is great.

— State and Liberty Clothing Company

The team is quick to respond and fix when we report issues. The tool is extremely helpful in our product workflows which require variations of product options.

— American Tarping

Absolutely amazing customer service, we were still on the old sc product options and they transferred everything over, including the option sets with conditions, and brought our legacy theme up to date to 2.0 super quickly. This new app is great as well, much smoother and many more options. Thanks again!

— Peitz Performance Tunes

Customer service is very important, and they deliver very well. Lina and Axel are usually the agents I get on chat, and they are always patient and helpful. The app itself works very well, the UI on this version is way better than the old system.

— Jayco Mailboxes

Great app with great customer service! I use this app extensively for some very complicated products and it works better than anything else we have tried. If there is ever a problem, customer service is very quick to help solve it. Thank you!

— Angel Competition Bikinis

I have been using this app for 10 years and I have the old Shopify 1.0 version. Each time this app has changed and there have been compatibility issues with my old store, the support team have quickly jumped in and fixed any issues very quickly. I just moved to Key Product Options and once again, the support team were amazing and migrated my old store over in very quick time. Thanks again to all t...

The Keystone team helped me set up my custom pet portrait store perfectly. The file upload feature works flawlessly and the support was outstanding. Highly recommend!

— Mi Loco Loco

a total car crash! product options have ben lost across multiple products. thousands of products. support is like dealing with a toddler. dont go there guys. looking for an alternative!

— Fat Chimp Forces Wear & Gifts

I'm reverting back to SCPO since this app does not support listing the product options separately at checkout. If can only bulk up the price of the existing product.

— PactCoupa

We were long-time users of Bold Product Options and later SC Product Options. When we were notified that SC Product Options was being discontinued, we were encouraged to migrate to Keystone Product Options. The migration process was extremely frustrating. SC Product Options worked perfectly with our highly customized Shopify theme, but Keystone initially did not. We spent a significant amount of...

I've had a good experience with this app so far. It's easy to use, the interface is clean, and everything works smoothly. The support team has also been very helpful—they respond quickly and resolve issues without much delay. Overall, it's been a reliable app, and I'd recommend giving it a try.

— MyBatua.in

Great experience! Their tech team helped me switch from SCPO and the transition was smooth. They helped me with all 3 of my websites and I'm so grateful for their support. I absolutely recommend this app!! The look of the options themselves on the page are cleaner too. Truly an upgrade! Thank you Keystone team!!

— PremadeCheerleadingMusic.com

Was not as easy to install as the Migration Guide indicated. Several steps were not as described, and then I found out I had a Shopify 1.0 Theme. I tried following the instructions for Legacy themes. Installing the Keystone code was ok, but there were no instructions about removing the SC Product Options code, which I had been using. I basically had to give up on my old Theme that I really lik...

— Simply Light Designs

Customer service is unmatched. They helped me set up 3 different web stores that all now use Keystone Product Options. They were attentive, easy to work with and communicated changes in a way that was easy for me to understand. Having used Bold Product Options and SC Options, this is the best looking upgrade yet by far. My highest recommendation for Keystone!

— FULL OUT Music Productions Custom

Still on the fence. I did the migration and played around in the admin and it still looked nothing like my current SCPO set up. The set up is also not as straightforward and easy like it claims and when I activated the Keystone app trying to make it close to what I had, it did not look good at all and I had to hide the app option on my product pages. The customization options in admin are not e...
