It's alright. Not anywhere near as nice as say TL in retention and breadth/amount of content available but they have a fair amount of zero-day scene RARed stuff as well as some non-RARed stuff. Not as much free leech as many other trackers either, if you sign up I strongly recommend trying to grab stuff while you have sitewide to build a buffer.
Oh and they do have pretty regular problems keeping the site up. People regularly get API request failures and the website can be unreachable for hours or more. Not a bad tracker but I wouldn't suggest using it as your only resource unless your needs are very specific such as only wanting day-one scene access.
