By austin B.
Incredibly fast shipping, and their in-stock notification alert worked great for a product I was waiting for! Top-notch service when I recently reached out to them as well.

They've always been on the ball with shipping speed, packaging, presentation, and availability of products. The very few times I had a small issue with an order, I had immediate responses with excellent options to resolve them. Wholeheartedly recommend this seller for buying your supplies.

Great products, fair pricing, fast shipping, and packaged well enough to withstand the rigors of delivery. Hope the move is going well to the new location and looking forward to doing more business with you all in the future. Almost done building my Voron 2.4R2!
