Worst 'professional' WordPress Plugin I've seen yet

We were under the impression that purchasing this plugin would reduce time spent in setting up a custom cart, as opposed to doing the custom programming for these custom fields.

We ended up being very mistaken about that…this is a very badly written plugin and the author should not be putting it out there as professional work. I think even on the student work level this would be questionable.

The interface is difficult to understand and unintuitive, the settings are archaic and difficult to understand. There is no documentation for a number of interface settings and the pictures in the documentation that’s there don’t match the current version. The code is buggy; Settings reset and delete as you try to use the very poorly designed/explained interface. The documentation is extremely vague and not written in clear English. We’ll likely be asking for a refund here, if they answer us back.

I wouldn’t waste your money on this plugin. I’ve only been developing with WordPress for about 2.5 years but I would say this is the weakest ‘professional’ plugin I’ve seen for WordPress yet.
