No confirmation bias here, I own an Ellis and a PM 1200 and the only Teknatool product I have ever owned is a lathe chuck, while it is good I prefer Oneway chucks. The Voyager is not a unicorn in the wild, there are quite a few out there and there have been zero reports of high runout either objective or subjective. What appears in the video would be extreme runout and noticeable to anyone without the need for a dial indicator. At the very worst the DP shown in the video is an anomoly.
I have simply been impressed with the ones I have seen.
