Hi Heraldo.
The P-100's seem to be doing fine. I have sold a few, and not had a single one back as yet. I have to admit, I have not done much flying on my own pair of P-100's but thats only because they arrives just as I was gearing up with new models for this year.
Pretty much an identical story on the P-140 Rx's
Not so good a news with the 180 Rx I am afraid, but thats covered in another thread.
Regards Al
