You get a green line in the very periphery of your right eye on the Vive, and you get concave blue lines on both eyes on the Rift. Depending on your headshape you can notice them.
The entire unit is cobbled together from off the shelf components in TPCast's race to be first-to-market.
Don't get me wrong, I am very thankful for their efforts as everybody and their mom was telling the VR community that wireless would be YEARS away, and they kind of pulled it off.
It's just that with known and big players such as Intel and DisplayLink now entering the market, I don't intend to send another € in TPCast's way.
Re calling them out on their bluff: look at the wording of their press release. They don't say they can deliver a full-bandwidth wireless solution for 3K, 5K and 8K headsets. They say that TPCast 2.0 is 'easy to adapt' to those resolutions. So if you were to say, 'alright, plug it in and let's see' they'll tell you that this will be supported at some time in the future.
It's the only way they can hope to stay relevant in the consumer's mind with the Intel solution having been announced to support the Pro's higher solution (which btw I'm still skeptical about as they didn't show it. Nor did anyone show if the dual cameras will be supported in wireless mode. I expect they won't, as we know exactly that the current Vive's camera requires the sort of bandwidth and latency that no wireless protocol under the sun can offer bi-directionally at this point).
