You can only see the price you have added to the slider. In addition, when you want to add products with variations, it disables all of them. When you want to add more than one slider, it accepts the price applied to whichever option you choose. No functions like addition, subtraction or multiplication. Sorry for your money. I say don't take it for granted. Go for alternatives. They also do not accept refunds.
We pride ourselves on our support service, in fact there are a lot of positive reviews about our support as well.
But there are always difficult customers. You didn't have any contact with the support team, simply because the plugin is working fine with what it described.
As for your request, the plugin doesn't say it will work with the product variant, you can't buy a plugin and then ask it to fit everything in your mind.
The plugin hasn't been updated since January. It needs so much more work
Thanks for your comments, but you can email us, instead of imprudent review here.
A few bugs. Will change when bugs are fixed
You should contact support team first. We always here.
