Very simple domain registrar and DNS host. Their prices are reasonable, and they don't try to throw hundreds of up-sells at you as other registrars often do.

It has a very good customer support. It's very easy and intuitive to use. Because it's fairly new in the market it doesn't show any ads.

Hover really nailed it on everything. Buying domains on the site is easy and no frills - the minimal upsells are unobtrusive and clearly labelled (you're unlikely to accidentally end up with something you don't want in your cart. Security is great; TFA and login auditing are features that make me feel much more comfortable. The interface is as intuitive as it gets. Clear labelling, smart design, and creative use of space lets the site feel open and uncluttered while putting all the necessary tools at your fingertips. The DNS editor is simple and lightweight - something that's getting harder and harder to find these days.
