Quality parts, fast shipping
Quality parts, extremely fast shipping. I would like to say they have great customer support but I have never needed to call. Everything arrived on time and in great shape. Can’t ask for anything else.

I’d heard good things about KB3D and placed a fairly small order, and I was really pleased when my order was fulfilled and shipped almost right away. Also, I had a couple of really nice stickers thrown in with my order, which is something I’ve actually paid certain vendors to include in my orders previously. I’ll definitely be ordering from here in the future

Excellent customer service, after reviewing my email receipt, I realized I ordered one item twice accidentally. I immediately emailed them and they responded quickly (same day) and refunded the item before shipping. All items received were well packaged and shipping was quick.
