Wanted to like this plugin. Paid for the premium version to get more accurate shipping rates, as we were frequently having issues with the weight based calculations on the free version, and losing money on our shipping due to it. I was never able to get the pro version to calculate shipping based on weight and packaging as it should do. I reached out a few times to the developer and never heard back. I will now have to find an alternative shipping plugin for my site.

After having an issue with the plugin (which ended up being a result of user error on my part), I reached out to Mike about looking into it. After a few emails back and forth I gave him some credentials to the site where he found the problem very quickly and resolved it without an issue, all the while providing me with very clear instructions on what adjustments I would have to make. Thank you!

As all the other comments mention, Mike gives an excellent speedy and personalized service. He even tweaked the plugin to add insurance for me. 5 stars, definitely better than you'll get with any large company. Thanks Mike!
