Scored on 25 merchant reviews we hold for Flash Cart‑ Drawer Cross‑sells, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.

Computed from the 25 reviews we hold, with 12-month windows measured to 2026-08. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 25. Open one to read it in full, with the developer's reply where there is one.

The app can suddenly crash randomly until you find out you have probably lost multiple sales due to customers not being able to get the cart to appear.

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...

Developer repliedHey Indigo Luna store! It doesn't appear that you're receiving our support replies by email currently. (Please check your spam folder just in case!) Our team has also tried to get in touch via your shop's contact form. Please email us at help@fluorecent.co, and provide us with an alternative email address that we can try to use to connect with your team. Show more

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. I reached out to Frederique with a specific ask and they were able to build out a custom solution for us to help us do even better this BFCM. Highly recommend!!

Developer repliedThank you!! We're so glad we were able to help out and we hope that the sale is a big success!! Show more

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). Already in-love with it and the team is just beyond amazing. They were very quick with their response and offered solutions that was very specific to our site.

LOVE LOVE LOVE this app so much!!! It is so user friendly, blends seamlessly with our theme, and it looks very sleek. Couldn't be more pleased...and the price is amazing!

Only have this running since 2 hours but both design and support are outstanding so far. Recommended!

Marcus really helped us with getting our cart sorted. We had an existing slide-out cart and a filter app that caused issues with Incentivize. But, Marcus and the team really worked on it the last few days and fixed it for us! Great service from the guys! Can't wait to see this app bring in that upsell revenue

Developer replied🙏 Glad we were able to help you out! Site's looking great, now I'm thirsty. Show more

Hands down the best app we've tried, it has increased daily sales some days up to 20%. Works flawlessly, fun to use with the shipping meter & great interface to upsell specific products at the right time. Really impressed.

Developer repliedThose are fantastic results! Glad you're liking it, let us know if you have any questions :) Show more
