Nothing, I'm not sure what to say about this product because it does exactly as advertised - register domains for cheap! The fact you can get one-year registrations at $4 per year makes me happy too :). There are no downsides either so far but if there's anything in particular we're looking forward then let us know ;) We've been using them since 2013 when they first came out with their service offering low prices compared other big players like GoDaddy or Namecheap (and others) who were charging more than double our current price tag of around 20€/yr just by registering an.eu TLD which was actually quite expensive back those days :).
