I purchased and downloaded the plugin, installed the plugin, and began using it get to see what results you would get performing a couple of variations. In my case it was selecting the following -
Setting Base Price
Selecting 1 of 5 variables in my first set.
Selecting 2 of 100 variables in my second set.
Selecting 1 of 3 in my last set.
I added the prices for those variants so combined they will equal the product price. When I finished it took about 5-6 minutes and when I went into products after it was completed none of the variables I even selected as an option (test above) were in my product variations. Furthermore there was a variation price that wasn't even remotely close that was a fixed price.
I then tested it again after deleting my 1 and only product, created a new product, added a few more variations from the test above and I had the same result. What was different this time is it only pulled in a maximum of 50 of these inaccurately calculated variations that I had never selected.
Grasping for anything to make this work because I need it I uninstalled it, and added the plugin for the second time with the same result. I checked for any other plugins that may have affected it and I pulled everything off with the exception of Woocommerce. Still had no bearing on it working whatsoever.
Conclusion - The product is HORRIBLE, based upon my analysis it is pure gimmickry that gives you check boxes and in the end all it does is activate the linking variations from the actual product variations. I've asked for a refund, I received an email asking for a screenshot of my variations. Bottom like is make 2 variations with 3 options each and you can see right thru it, I will update if I get refund. Looks like a nice product but clearly needs work to get better.
