I've had this board for a year, but have only actively used it for the last month.
When I initially received this board from Massdrop last year, the left shift key did not work. I did not receive any communication from MD, after multiple tickets. I opened the keyboard case, and discovered a very poor soldering job on the switch. I de-soldered the switch, then re-soldered it, and it started working.
I started using the board as my main about a month ago. In that time, I've noticed strange flickers in the RGB, and some keychatter. The flickers have been getting worse. The board has now started dropping keypresses altogether.
For those of you who have joined this drop, be aware of serious quality issues from this manufacturer. For those that are interested in buying the board but have not joined the drop, understand that this board is cheap for a very good reason.
