the only flaw for my taste is the microphone which is particularly short, we really can close the lips and is a little too rigid, especially its installation is quite tricky because there is a small tab that must go into a small notch is really quite difficult to visualize, and thus it happens that we not catch correctly the microphone and after it is very hard to remove it as it glides still deeply enough into the slot even if the latch is not correctly opposite the slot.
So it is best to be very careful when installing and do not remove it to avoid damaging the DIMM.
