I like the fact that I can find all the domain names I want with one search. I like that you can filter by extension. I dislike that in some cases, the name might not be a correct spelling of what you are looking for. Also, sometimes if you search for a specific domain, it will not pop up in the results. It is great for searching by extension. It also allows you to look up extensions that you use for your own website. You can also find out if a domain is available or not. The speed at which it updates is great! It's very easy to use as well. I like that you can search by TLD or extension with ease. Sometimes when searching for extensions, there aren't any results found. This isn't always the case but sometimes they don't have what you're looking for. Great tool if your into SEO/SEM. You will be able to find all sorts of information about domain names.
