I've had a few things from them over the last few months. They send a new email each day with about three new brands on offer. Things last a week so there are normally at least a dozen brands on offer at any one time.
Brands are a mixture of obscure/rubbish-looking gear and "sports nutrition" products alongside some very decent stuff.
I've had some Pearl Izumi stuff from them before as well as a very good sleeping mat (Hyalite Peak Elite). They have some high-end brands like Haglofs from time to time.
Do be aware as others have said that delivery is slow - could be about a month - it will arrive though. No experience of customer service.
Well worth signing up if you don't mind a daily email (which I presume you can unsubscribe from without losing access).
