Great work, thanks!
P14 max are available now, do you have plans to test it anytime?
Yes, waiting for it to arrive from Arctic.
Great review as always, thanx
One small typo on the 2nd site, last sentence. There should be superior.
…not the 1st typo in this exact word … I have two guesses for the reason:
1st: superior in Greek = ανώτερος [anóteros] …phonetically close prefix an ≈ in…. or
2nd: you work too hard (almost every day one YouTube video and one review + other activities) … you should rest more, not just work … in Slovakia we have a saying… work is not a rabbit, it will not run away, it will wait at you … 😊
thank you! No rest for me 🙂
