I am back with a winter review,
The tire behaves just fine until around -5 degrees on dry/wet/ asphalt and are good on mud or a little fresh snow.
On old frozen snow however they will get you moving, but you don't feel that the tire grips in any way, these tires will allow you to move slowly in a mostly straight direction. Basically you give a little gas and hope that you move somewhere, every second on snow will sound nerve-wracking - still the traction control will rarely intervene. If there is ice the car will just slide randomly when braking but the tires allow you to always stop. If you keep the speed steady and slow it maintains direction without issues even in tight corners, when you lose control the car just slides and the only thing you can do is to stop it.
My car is RWD and I wouldn't really dare to go up a large hill with snow/ice with these tires unless absolutely necessary. The car slides/spins in place whenever one has to go up on an icy/snowy ramp from a full stop. They will get you up the hill if you insist, but if you don't have a lot of space around you will slide left-right and hit the edge of the road.
At around -10 degrees or lower it starts to feel too hard and slides as soon as you hit some gravel with ice/snow on a half cleaned road, brake a little harder and you slide like a sleigh. I don't know if I would want to test these without snow chains/socks at -20 degrees or lower and fully snow covered roads because the lower the temperature the lower the feel of grip in the steering wheel.
TLDR: I won't say it's a bad tire because it will allow you to move and stop just fine if you have space, otherwise the car felt like a sleigh going sideways more than I would have liked. I managed to get up and down on 20-30% ramps with snow, however in very tight spaces I was very lucky that I didn't hit the car because the car slid sideways a lot when braking. You have to also always pay attention when joining a main road from a snowy road, the rear tires will slide sideways.
