Amazon is more expensive, but I ordered on Thursday and had them Friday (yesterday).
Here is a quick write-up of my impressions after first use:
To start, the goggles are surprising light for their size, and the plastic is very rigid and of good quality. No creaking or bending/twisting. The velcro straps worked well for me and required minimal adjustments, though it remains to be seen how they hold up over time. The velcro patches are large, so hopefully they will outlive the goggles. My biggest complaint is that I haven't been able to position the goggles so that I can see the full screen -- the bottom 5 to 10% are cut off, and I'm unable to bring the screen down further because the goggles are already sitting on the bridge of my nose.
Also, I was surprised to see the complete ST16 screen mirrored on the SkyView goggles. I don't know why, but I was under the impression that the HDMI output was just the video without the telemetry. I actually much prefer this arrangement because it lets you see the altitude, speed, direction home, recording status etc.
My whole reason for getting these goggles was to eliminate glare and make flying in bright lighting more practical and enjoyable. In this respect, the goggles succeed brilliantly. The picture is very good with enough resolution to display a clear picture and reproduce the ST16 interface, though you won't have trouble seeing individual pixels. I did a test flight around 2PM in bright overhead sunlight which made viewing the ST16's screen or looking up at the bird a pain (literally), but using the SkyView goggles was pleasant.
When I first unpacked the goggles I thought that the included HDMI cable was a bit on the short side, but in practice that isn't the case because of the proximity of the ST16 to the goggles.
One thing that is awkward is keeping the goggles ready when you're not actually using them, such as during takeoff and landing where you probably want to view the bird with your own eyes rather than looking at what the camera is recording. I have been tilting the goggles back on my head so that they sit on my upper forehead, but that isn't the most secure arrangement and must look even goofier than wearing them.
