If you are on the fence, just do it. We've all used a million of these but Linke.ro is very well thought out, super responsive and modern. I had zero issues and zero bugs. The bio sites load very quickly (which is a problem I have with other ones I have used). The custom domain per bio page is a nice plus. As advertised, it only takes a few minutes to build. I did spend quite a bit of time customizing - you will find there are plenty of options to really make your bio site unique. Five sites is more than fair for what you get (guys c'mon it's a little over $10 per site lifetime ). I have emailed support and they are very responsive. If I had to find constructive feedback, I suppose I would ask for the ability to add my own custom css, but honestly I am pretty happy with what options were already available. All around very impressed and would highly recommend.
