Joyfully unpacked the gums and once equipped about 10 keys with the gums and a writing sample on my MX-Board 3.0 (brown) performed.
But just as I was looking forward to the rubber, the desire was gone the other buttons also to be equipped with the rubber quickly. Because the keys which I had stocked have, sometimes not triggered a clean contact more so that letters have been swallowed. The idea with the gum is certainly very good. However, due to certain thickness, the Tastenhubweg is also low, which is why you probably reaches the threshold of the switch changeover.
From the acoustic side, the affected keys have been significantly dampened. So I would give the gums 4 stars because I would have expected more cushioning.
On the part of the contact dropouts, I can give the gums only one star.
Power together 2.5 stars.
So whom individual keys dropouts matter, which is well served by the gums. Who is, however, dependent on clean key contact that should not affect the gums definitely gone. Otherwise, he throws the keyboard from either the window or may again abpulen over 100 key caps to remove the gum again.
