Yes, they don't just sell measuring equipment, they also know what they are offering...
I always find it very pleasant when you talk to people who know exactly what you are talking about and can react accordingly.
What I find a pity about the demo board is that they couldn't keep the price below €200 in the long term.
In the beginning, at least a lot of people "here" ordered the board, which I thought was great, because we all have the same source here, so it's easier to understand the problems/measurement situations of other users.
A board as a reference, so to speak.
So please make the board more affordable again.
