***Update: I recently had a small issue with the Quick add to cart in my search bar, yet the customer service provided was amazing! They replied to me the same day, and the day after the problem was gone!

I've been looking for a way to allow my customers to buy products directly from the collection pages, by choosing among the different variants. I did try a couple of Apps like Product List Variants or Nice Add to Cart, but I have to say that this one is much better. It would be even better if we could have more customizable options, especially on the quick Add to cart for collections, like different shapes of a button, or a full button, visible variants or all grouped, and so on. I am very satisfied with the app and it's definitely worth the money. Hope you guys will keep up the good work!

It's looks pretty good ! I can't wait to use it properly and make a right feedback to the shopify community

support team fast respond, i like it, this save me a lot of time. and i also like the animation in the app

The Sticky Add To Cart app works as expected and renders well on mobile where most of our visitors come from. Customer support was helpful and available when called upon.

Fast and very useful application with responsive customer service. I use it for the sticky cart bar on my products. And I use the sticky cart during "buy one get one" offers

So far so good. Although, it would be great if we could customize the the colors of the buttons. Maybe through CSS this is possible. Great add to the store nonetheless.

excelente aplicación doy cinco estrellas por el excelente servicio que la aplicación brinda a mi y a mis clientes

i think this investigation is it worth to bring my shop to a new level. hope this really works......

Top notch support (I was lucky to be helped by Mohit K.), the app works pretty fine, but be sure to add a code from their knowledge base (https://codeinero.helpscoutdocs.com/article/39-how-to-make-add-to-cart-checkout-booster-pro-load-faster) if you want the app to load asap :)
I‘ve tried a couple of other apps which added sticky ATC button, but this one performs the best. So, yeah, indeed I can recommend this one.
