The first pair lasted 4 years with hard use, walking on mountains, asphalt, dirt, and seawater. The second pair, with all the above plus oil, lubricants, petrol, does not slip and is waterproof in the rain. If you pass through water above the ankle and they are loosely tightened, they let in a little water, but if they are tightly tightened, there is no problem. Overall, they are very reliable, comfortable, and definitely require a smaller size than what you normally wear. They have a comfortable D-line design, and the rotating gel under the sole has 4 settings for walking on flat surfaces, rough terrain, jumping, and static use. It is very helpful. I am very satisfied and I would gladly buy them again! Finally, I would like to emphasize that all of the above was tested in a Mediterranean climate. I do not recommend them for extreme temperatures below -5 degrees Celsius or extreme heat above 40 degrees Celsius, especially when exposed to direct sunlight in static use, as the foot literally boils inside despite being breathable and quickly removes moisture from the foot.
Update 10/6/2020: Several friends have fallen for counterfeits and they fell apart within 6 months. Be careful to ensure they are genuine. Also, I have friends who bought the cheapest model of the company, ranging from 70 to 90 euros, and they said it is decent, but in 4 years, the sole on the sides opened and came off, and they had to glue it or replace it. However, my own pair is still holding up well with daily use at work, and I haven't had to deal with any maintenance issues. I remember this whenever I think about it.
