Oxyhealth review for Hulk Bundles Quantity Breaks

This app has got worse and worse since more users are using it. This app relies on api calls to their own servers, which slows down your checkout. As of today, their server is down, with a 503 error showing in my shopify apps admin section, and a greyed out 'add to cart' button on my website cart page, meaning no-one can purchase from my store. Ive had to roll back my theme 6 months to get rid of their code as an uninstall does not fix this issue. The developers behind this take days to respond to tickets. Be aware that installing this app means that your cart will be slower and that if any issues arise your cart button will not work. I guess this is the price you pay for using a free app!
