Reasonably fast and solid quality, could be better
I recently placed an order for a custom printed keycap from Goblintechkeys. The item shipped reasonably fast, and I was impressed with how sharp the dye-sublimation turned out. The edges of the keycap itself came a little warped due to the heat from the 5-side dye sublimation process. It's not warped enough to affect use, but some might be able to spot it at a glance. I'm personally fine with it and I liked the shopping experience enough to buy from Goblintechkeys again.
