I have been using it for about 10 days.
It is warm as it should be without being annoying.
I got it in the off-white color. However, it doesn't affect me anywhere once it's in duvet covers.
At first, I thought it was thin, but not at all. It is as thick as it should be and has a normal weight.
The 95%-5% (down-feather) is ideal for me, as the 50%-50% is much thicker and would be too heavy for me, and economically they have a small difference.
On the other hand, the 100% down has double the price. It will definitely be warmer, but I believe that with this one I will be covered.
Personally, I recommend it.

Excellent. Tested for 15 days, sleeping in a room around 20 degrees with short sleeves. Very lightweight, with proper seams so that the feathers do not move. Worth its money (purchased on Black Friday for €161).

The duvet is a real pleasure, while it is so thin and light when you lift it, when you are covered with it you feel like it has double the weight from the warmth it creates. The down makes all the difference, I am very satisfied with the purchase.

It is amazing! It is thin and quickly reaches body temperature! I had a down comforter before, but this is the best!
