After 2 years of use, I have to say the following:
Firstly, it is a very good winter glove.
However, it also has its negatives.
Up to 10 degrees, the sensation is okay. Below 5 degrees, the hand is cold. I can tolerate it, but my hands are cold. Below that, it doesn't provide enough coverage. The perfect combination is with heated grips. You won't solve the cold problem in any other way.
As for waterproofing, I happened to use them for 20 minutes in the rain and when I took them off, they had collected moisture inside. However, while wearing them, not a drop entered. The same happened when I drove for 1 hour straight in heavy rain. Not a drop entered, but when I took them off, I dried them immediately.
What you pay for is the waterproofing. Beyond that, you definitely need heated grips to keep your hands warm at all times.

The purchase was made in late January '23.
On the positive side,
it is a very beautiful glove with very good quality materials and a very good level of protection.
Warm glove. On a trip I took in February to the mountains of Epirus at 2 degrees Celsius, I was not bothered by the cold for a moment.
I have not tested it in the rain, but my experience with the Gore-Tex membrane suggests that it will do exactly what it says.
The special surfaces on the index and thumb work perfectly when using the phone.
The size, in my case and in many reviews I have read, is correct.
Although it is an expensive glove for my pocket, I consider its price to make it an even more interesting glove.
Inevitably, it is a thick glove with alternating layers of waterproofing and insulation, resulting in a relatively vague feeling of the controls. Not so much on the clutch/brake levers, but on the switches and especially on the handling of the visor and helmet ventilation buttons. But as I said, the partial loss of sensation in winter gloves is inevitable.
On the negative side,
the patent for the automatic tightening, although it works in tightening, unfortunately does not open as much as it should and entering the hand into the glove is tight and requires effort.
The internal linings (insulation and waterproofing) roll up when removing the glove, which contributes to an even more difficult entry of the palm the next time the glove is worn.
My solution regarding the internal linings is to pull the fingertips before taking off the glove.
When I wear the glove, I hold and pull outwards the inner waterproof "sock" of the glove, which facilitates the entry of the fingers into the inner linings without them rolling up.
The patent for the automatic tightening does not bother once the glove is worn, on the contrary, you feel the glove securely fastened to your hand, but it remains the only difficult point when entering the palm when wearing the glove. However, I have no intention of cutting it as I hear from others because it really works and serves its purpose in tightening.
Given that the glove offers everything it claims and at an excellent price, I overlook the tight entry (because at least in fastening, the patent really serves its purpose), I also overlook the linings (expected in a winter glove) because they keep my hands warm, and I give this glove a 5 out of 5.

The purchase was made in early December and I waited for the first frost to write my review.

On the positive side, it is a glove that when worn, you feel protected. All the reinforcements are there for the right reason and do not bother, even the hard protective on the knuckles. The quality is top-notch, both in the material of the palm (goat leather) and the rest of the glove. In temperatures below 2 degrees Celsius and for a 7 km ride, my hands were warm (*). I tested it in rain for about 10 minutes and had no problem. The inner sock, which goes inside the jacket, prevents water from getting through, providing additional protection.

On the negative side, the company has launched a patent for an automatic tightening strap, which makes it difficult to put on because it tightens at the entry point of the hand. In reviews I read about other gloves from the same company with the same patent, some people wrote that it has cut them. I simply do not use the tightening strap, but overall it is not convenient at all. Using the phone is not easy, it does not have good responsiveness, partly due to the size. I bought a Large, the size I usually wear.

Regarding the size, it is good to try the glove before purchasing it. I followed the company's chart and based on the diameter, I chose Large. It fits well on the hand, not tight, but on the fingers, because I do not have relatively long fingers, it is a bit too much, making it difficult for me to handle the phone.

(*) Tip: keep the gloves at home and not on the motorcycle, so they are warm when you wear them (not on a radiator) and keep your hands warm as well. I tried it and saw a big difference compared to the times I left the gloves in the trunk.

I would give it 5 stars because the gloves are very good. However, this patent makes them a bit difficult to wear.

Update:
1. The tightening strap was cut (very carefully) and now the glove is comfortable to wear.
2. A serious (for me) downside is that if the hand sweats, it sticks to the fleece lining and is impossible to put on. I tried to wear it after the gym and preferred to drive with bare hands. For traveling, putting on and taking off is excellent, but for everyday use, it's better to leave it.
