LKM died after 1 year of work, it works, sticks, thinks, comes off. Used every day, but for 2-3 hours and mostly in Photoshop and Lightroom. Those. With active use, up to a year, it would not have lasted. Now I think that probably with the current quality it is worth looking at competitors, because. 2500 thousand for 1.5 years of NOT active use, this is probably not normal. This is not a complaint, but I vote in and will continue to choose another manufacturer.
