Hi Tt,
March 2016, I purchased a Thermaltake Poseidon Z RGB Brown. In the last month, I have noticed some Chattering or Double key similar to the issues mentioned frequently throughout this thread.
While working apart of a service desk, I have ran through the common troubleshooting steps.
-Different USB port
-Different PC
-Removed Keycap
-Cleaned the surface area.
Even though I have tried all this I have noticed that the problem is still persistent.
Please note, I live In Australia. Who would be the best point of contact in regards to an RMA?
Kind Regards,
Dynamik (Peter )
