King Product Options & Variant

Amazing app. So many customisations are available and support responded so quickly when I experienced an issue. Would most definitely recommend it to everyone.

Support is phenomenal and and truly supportive :) Who knew!
Not only has this app allowed me to make reasonably complicated product options easy to implement, the staff are top notch and customer support is amazing.

Works out of the box. Happy With what it can offer considering the price. Would recommend this to other shop owners that are starting out.

Installed the app within minutes, easy to navigate settings. I had an error and the helpdesk solved the problem in minutes. Exceptional customer service.

The app was working fine before, but now for past 3-4 days, the upload an image option and text options are not working on my website. Please look into this.

Customer service is spot-on. The new app version looks a lot better and works better too. Good job from these guys and excellent support. Give them a try you will be very happy with them.

The app works great! At first I couldn't figure it out but the customer support team fixed it really quickly! Thank you for this awesome free app!

It's a very handy free app with amazing customer support. They respond lightning fast and fix any issues you might have just as quickly. I can only recommend! :)

This is a great app and does exactly what we wanted. Also, absolutely first class and incredible help when we needed it. I asked a few questions, and within a very short space of time they didn't just reply, they'd made some changes for me.
Excellent!

It really is a good app, but I knocked off a star for two reasons:

First, the dearth of documentation. The FAQ link goes to a table of contents, but all of the links (to faq.ymq.cool) appear to be dead, and have been since I installed the app.

Second, there is no visual indication of when a variant is sold out. Yes, you still see Shopify's "Sold Out," but the swatch looks like all the others. There are settings that let you load an image (via URL) and change the border for disabled variants, but they don't function. While this may sound like a minor issue, I know I find it frustrating to have to click a button before I can see if something is in stock—I want to know at a glance—and I'm concerned that my customers will feel the same way.

This message is both a review, and, since none of this is documented, a warning to those who may be trying to get the function to work that it's not you: It's a problem with the app.

That said, I know from reading other reviews and responses that this is a two-man operation and that they're creating and supporting numerous apps. This Product Options app adds a GREAT DEAL of functionality that Shopify does not natively, and it's clear that they have tweaked and added additional features based on customer input. I don't like to slam the creators who allow us to do things that Shopify does not—particularly for free!—and that is not my intention here, but I wasted a lot of time trying to figure out what I was doing wrong when, in fact, I wasn't. Hopefully this will save someone else that time.
