I didn't have any issues when using it, but in most cases you can only use one language per page? That's kind of lame since not everyone knows english by heart. It would be nice if it had more languages available for the end user instead of being locked into that 1 language. We love how well it integrates with our site. The ease of setup is amazing! In just minutes we were up and running with our new feature. Our users love its functionality so there are no complaints from them at all. Also having the ability to monitor feedback and trends is super helpful. LikeBtn is easy to integrate into your website. It's free and open source. I like that you can easily change the look and feel of your like button. I can't think of anything I dislike about LikeBtn. If you are looking for a simple and easy to use like button for your website, I highly recommend LikeBtn. I use LikeBtn to like and dislike certain things on my website. It is a great way for my readers to interact with my website and my blog.
