Honestly, one of the best companies I've purchased with. I've had good and bad experience with printer parts - kb3d is hands down a standout. Prompt response, authentic customer service, and they got an annoyingly large order together and shipped in like 2 days amongst probably 1000 other black Friday orders. Really hope the best for them.
