Reliable and serious, not the cheapest
I have had a few dozens of my domain names with them since I feel they are safe there. I moved however a number of domains out due to the prices - not the highest in the industry, but not the cheapest either.
I would recommend them without any hesitation. They are reliable, not US-based (Monaco), and their service is solid.
The minuses: no free redirection (can be added against a fee), interface is not the most pleasant or easiest to use.
Nevertheless, a good solution - I will continue to use it for some of my domain names.
