The items discussed here has been (separately) seen on this forum, but a direct comparison has never been done.
For quite obvious reason (the possibility of and easy mount of filters, especially PL) I would like to replace the original Q3 hood with a vented one. Excluding a priori both the original Leica as well the Overgaard for their insane price (I can't see a real justification for that madness), the remaining possibilities looks like to be two: JJC and Haoge. Both have already be seen here, anyway here are the links to get them from Amazon (black version):
JJC: https://www.amazon.com/JJC-Cameras-Replaces-Center-Vignetting/dp/B0CL25Y5FB?sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY
Haoge: https://www.amazon.com/Haoge-Metal-Typ116-Camera-LH-LQOB/dp/B0CD43VTGY
They looks like very, very similar (apparently there are very slight differences in the specs), so I'm undecided between one of them. Maybe there are differences which are not obvious on Amazon, but instead important in reality (even some review say that they could cause vignetting... something quite strange to me)
I would like to get opinions before choose one of them.
(The ideal would be if someone had had the opportunity to compare both them directly, but this, frankly, seems quite unlikely to me)
What do you think about these hoods?
Many thanks in advance for any help!
