Ordered my Gadget Infinity V2 Cactus triggers on e-bay April 30, and received today, May 09. So just 8 business days Hong Kong to Canada, very fast.
The build quality is good, and sturdy enough for the job of holding my 580 on a light stand at different angles. The base foot is metal and did not twist or turn. The plastic construction is not NASA grade, but again certainly up to the job it will be asked to do.
It came with a battery, and worked perfectly the first time. I plan to add to this thread later when I have a chance to test more fully. For now here are a couple of pics:
