Here's a warning from the Think6.5 GB which was also produced by GrayStudio. Avoid to save yourself a headache
"So many problems in this GB has arisen. The board is amazing but the logistics have been a nightmare.
First of all the GB runner Oldcat seems to have disappeared from the face of the earth, leaving all the communication duties to his moderator on discord. On Graystudio's side, shipping has constantly been pushed back with little to no updates from Potter even after deadlines have been crossed. I've paid the shipping invoice over a month ago and still have no idea when the board will be shipped out. Potter claims he would have shipped it out 2 weeks ago but continues to cover it up with excuses.
Second of all the pcbs (especially the hotswap ones) have had tons of issues. There has been reports of LEDs malfunctioning, diodes soldered in the wrong direction, and hotswap sockets not soldered on properly. The whole point of hotswap pcbs is to lower the barrier of entry in this hobby and eliminate soldering for newcomers. The hotswap socket issues force new users in the community to buy soldering tools to fix the mistakes made by Graystudio. I cannot endorse GrayStudio any longer. This isn't the first time. Space65's shipping was a sh*tshow as well. Save yourself a headache and avoid this manufacturer. I will reiterate this on GrayStudio's future group buy threads to warn others. "
