A Great Company
Every time I order from KB3D things are shipped quickly and arrive quickly. They always have things in stock and are super responsive to inquiries. I cannot ask for better customer service.

I've now ordered 3 items, and received fantastic service. I will be ordering more parts/kits in the future. Thank you

I have purchased from KB3D three times already and so far any problems nor regrets. Description of the items is accurate and reflects what you receive. There is communication but when items are mailed it very easy tracking. Good job running good and reliable service. Cheers.

Quick ship and quality parts - a perfect experience. My order (GE5C spherical bearings) were shipped quickly (I believe it was within a business day) and are exactly what I need.
