One of my fav apps and a must have. Support is amazing and they help within 24 hours, and the app itself makes your store look so much cleaner. Highly recommended for any shopify store.

The best ROI of any app I have in my store. I started using these guys back when they were Obsidian upsell and it was an instant success. In the years/months since they've only gotten BETTER. Their cart is a super simple install and has a ton of features that drive big $$$ for us.

We've been exploring many apps but none integrated beautifully and seamlessly with our theme as Flash Cart did (which is also developed by Fluorescent team).

— Cavaier

The app has good potential, but bugs appear too frequently. While customer service takes too long to respond to an email or there is no chat to contact anyone. I have been waiting 4 days to fix a problem with the currency in the Progres Shipping bar...

— Indigo Luna Store

everything is fine :) would love to have more options like UpCart has (ie the option to directly write a coupon code inside the cart drawer). and more flexibility in adding own icons below the Go to checkout button
