You’re quite incorrect about the assertion that PH2 is the “same design as PH1”, while suggesting PH3 is “new and improved”.
Can you please list the similarities between PH2 and PH1, while simultaneously showing how PH3 implements that design feature differently?
I think a rigorous examination of the facts will show that the PH2 is quite a bit closer in design to the PH3 than it is the PH1. But then with a few features added which PH3 doesn’t even have. (3rd IMU, IMU heating, etc.)
Kevin, as somebody who is unbiased, I buy hardware from several vendors depending one which is most suitable for my needs (including Drotek), I find this comment from you disappointing.
