King Product Options & Variant,662 reviews

Works really well, have set up various option templates. very impressed with their customer service. does exactly what i needed the app to do.

Very happy about this app. It does exactly what is described, and more...
When I needed the support, they answered very quickly with the right solution. Furthermore, if you don't need advanced features, it's free. Good job.

Had some trouble getting it set up but their customer service was VERY quick to respond (even at 10pm at night on a Friday)! Now that we have everything set up its running very smoothly.

Excellent service, this app works best to create all types of variations and customer support is just mind-blowing, quick reply and willingness to help is just exceptional.
Thanks again.

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.

Use this on 2 stores, always have some problems with it. Randomly an option stop working, and my customers are unable to purchase. Only the last week spent £500 on advertising, and my customers were unable to purchase, because an option did not work. Took us 1 week to realise why we don't have a single sale. You guys need to take business more siriously, because it happened to 2 of my stores already. We Business owners can not afford to loose a single penny because of an app. Choose a more expensive but better app guys.

I'm amazed by the app's incredible power, and what's even more astonishing is that it's available for free. This app provides everything I desired and the customer service is exceptional. Highly recommend.

Very useful app, this app helps our pages a lot! Also super quick response! Can't believe this is free.

Have used all most product option apps but King app completely stands out. It has almost every feature of paid apps.

They were very helpful when I was trying out a new theme, because at first it didn't work. They were very patient and after their persistence in ensuring all was OK, it now works very well. Thank you guys!
