I really wanted to like this plugin. The design has a lot of promise. Unfortunately it is hobbled by some troublesome free template implementations that made me have to spend time on alternatives and wonder if it will reach its potential.
For International sites - the count down template doesn't recognize international date standards so if your site isn't set on a US time zone - that feature of a template (which was a must have for us) won't work. When you see things like that - you begin to wonder.
If you need to use shortcodes (as we tried to get around the above problem with some count down plugins) - support is spotty at best. Some editor fields accept them, some don't, and some just give erratic results - in the same template and support varies from template to template.
Some templates will allow you to turn off their embedded social icons and some won't. Frankly - if the templates fully supported other plugins - those social icons just wouldn't be necessary.
There are a number of other small issues - but we reached the point that the issues that kept turning up led us to have to consider alternatives. We came to the conclusion that right now the templates are not well tested and curated.
