1. There is some coding necessary to get the app running - but it is not very difficult, because there is a good tutorial. That was the only positive point.
2. After coding, we put some colours,patterns etc. in the app - 24 h later, we weren't able to change anything, app was kind of freezed for changing swatches.
3. We wrote the customer support - it took about 24 h to get an answer. In our opinion, very slow if something is not working.
4. We granted access to the shop - the engineers worked on the app - and then the worst thing happened, they uploaded stuff wrong (we changed it manually) but after they worked in the store, the store was crashed, drop down menues etc, everything had an error and we had to upload a shop backup, cause we weren't able to fix it.
5. Last point, customer service always wrote our name wrong, after we told them, that we are not called like that, the answer was with the same wrong name. That is just a small thing, but does not look, like each customer is appreciated.

Think about using this app - it took us around two days where nothing worked and we decided to use an other app from the store, that works better.

This features this app adds is pretty valuable (to me). If customers can't see multiple variants from the collection page, there's a much lower chance they will make it to the product page. Easy to set up. Minimal adjustments once it's set up. It just works. This is the only viable app I found that does exactly what I wanted to do.

I did have one hiccup with uploading one specific swatch image, but it wasn't major and support helped me get it resolved. Honestly, I really thought it was silly that Shopify does not have this feature built-in. In my opinion, it seems logical that any store with multiple variants of a product would want to show that they have multiple variants of products. My customers didn't even know I had other colors (if they never went to the product page) before I got Collection Swatch Pug set up. Excellent app.

Very nice app. Works as intended and if you have problems, the support will find a way to help you. They fixed my problems within a day and changed the code of my store so that the swatches and images on the collection page change at the same time.
Thanks again and keep up the good work!
