We've used this app for a while, has been great to show customers the 'stock status' of our products.
Great app to use for it's simplicity to set up - Tom was also very helpful. Only not 5 stars as it doesn't have the ability to schedule the bagdes/banners (yet!)
fyi - ⏰ scheduling is now available for badges and banners in Flair
We found the app easy to use. We had some issues on placing the badges, but the support from developers is really good. They handled our problem quickly and resolved all the issues.
