My short experience with P515.
Sale via Ali from the EU shop went very well, delivery took 3-4 days more then expected. Crank looks very good, marginal heavier than the 105. Assembly was also no problem, I ordered it with the QED chainrings. Installation on my Lightcarbon LCR017 was not a big problem, I did however have to add a spacer on the drive side because otherwise there would have been play between the two arms. First 100k tour was also problem-free, recording in. Compared to the power meter pedals seems to be lower in the numbers, maybe still needs to be calibrated. What I also noticed is that the QED chainrings are louder than my 105 crank.
I hope this can help you a little.
Best regards.
