New Pixel King E-TTL flash radio triggers

I just received a set of new Pixel King E-TTL radio triggers and I must say am very impressed.  I purchased transmitter/receiver pair from eBay for about AUD$150: http://www.ebay.com.au/itm/PIXEL-KING-E-TTL-Wireless-Flash-Trigger-CANON-F369-/150659391128?pt=AU_Flashes&hash=item2313ffde98

I set them up with my Canon 5D mark II and 580exII speedlites.  The E-TTL works really well and supports A,B & C groups in normal & high speed sync.  Second curtain sync dent work and group ratios are not supported making the use of multiple speedlites less than ideal for creative work.  One other odd thing is the hotshot on top of the transmitter doesn't function, so you can't use an on-camera fill flash with this setup.  BUT...manual mode is awesome!  You can use the 3 groups and set individual power settings and zoom settings for each group all from the back of the 5DmkII menu system.  This is fantastic when using the Westcott soft box that normally requires a wrestling match to change a power/zoom setting on the speedlite inside.  You can swap between E-TTL & manual from the camera as well - everything plays along.

These units use a radio frequency of 2.4Ghz and so don't suffer the issues that the Pocket Wizards have with interference when using 580ExII speedlites.

A USB connection is supported to allow firmware upgrades, so I am hoping the E-TTL group ratio aspect will be fixed in time.
