Health Harmonic review for Buy Button channel

I think this app sucks and needs to be re-developed. The buttons can't be customized well and slow the page load down to a crawl on pages where I've put them. Please develop an improved version that actually allows you to create "Amazon style" buttons or other easy to read buttons. Reply to dev response: You haven't addressed any of my concerns: SLOW LOAD TIME (why?), poor graphic controls, not easy to read, poor conversion. I won't hire a shopify expert when I can just not use this stupid app! I can create my own buttons with an external cart URL and it works fine and doesn't slow down my site. The point of an app like this should be for DIY not to hire an expert! I've tweaked CSS myself on quite a few apps to create great looking buttons that convert well on my (non-shopify) pages so why make this one so locked down and dysfunctional? This app sucks just get rid of it or start over and redevelop it! Clearly I'm not the only one who feels this way since 38 people gave it one star likely because we can't give it zero.
