Non-coder here. This is definitely the best currency plugin for WordPress, and I tried quite a few. It's very customizable and has a wide functionality. I'm very happy not to have had to install any e-commerce plugins in order for it to function.

I would give it 5-stars, but the instructions for use and installation could be clearer for non-experts. I had to tinker with it quite a bit to figure out how to set it up. I'm a very literal instruction follower, so there are details, small actions, or terminology that are assumed and skipped or glossed over (presumably because most users know more than me). But, since my work involves writing instructions pretty frequently and am generally good at troubleshooting tech, I feel like it's likely that others will encounter the same hurdles.
