I like that it is cheap but also quite good in terms of service (the support team are always really helpful). The price point for their products seems to be set too high - you're paying more than other registrars because they have better prices available elsewhere! They don't offer any way to purchase domains from outside Europe so if your business needs international customers this could cause problems. We needed one or two extra top level.com's at very short notice when we were about launching our new website which caused us some issues with others who had registered those names previously etc., however register was quick enough after registering them through another provider not being able to do anything until then (but still cheaper!).
