Logitech G810 Keyboard, any Logitech keyboard with Romer-G switches, Logitech mechanical keyboards and Logitech generally.
- Especially the little stems of 90% of keycaps on my G810 keyboard are broken. And that's why some keycaps are now became so loose that when I turn the keyboard upside down, some keycaps fall the the ground

And upon close inspection, the bigger pins/stems of almost all the keycaps also began cracking, indicating that they will also break in the future.
- Even tough their Romer-G switches are especially manufactured with double contact mechanism to eliminate chatter, they still do CHATTER and what's worse is they sometimes misregister also.
- The G810 Keyboard has a terrible annoying "ping" noise accompanied with every key press.
- The typing feel of Romer-G switches are mushy, soft and generally unpleasent. Not as solid and snappy like a Cherry MX Brown feel.
- Their Cherry MX based mechanical keyboard keycaps stems also break.
- Their implementation of RGB lighting is problematic. You can't obtain a pleasent bright white light. It either becomes pinkish, bluish or greenish.
- In short, there is a huge durability and reliability problem of Logitech Keyboards. I was wrong to choose Logitech. I only have a Logitech Z200 speaker system now. From now on it's almost impossible for me to buy a Logitech product again if they continue releasing these type of products.
Here is a photograph of 2 of my G810's keycaps:
(Mind you as I said before, almost 90% of keycaps are more or less in this situation. )
