DavecUK - the point being here is not about the talk and the marketing. It’s about demonstrating what the product can do to their prospective buyers, beyond the glossy video with background music.
The Niche Zero was the exception, where, prior to the funding campaign, the grinder was dissected (literally) by you, with lots of videos showing in great detail what that grinder was capable off - The only reason why I was a Super Early Bird supporter.
Unfortunately I haven’t seen this for the items I mentioned above.
