Not sure if this is the proper location for this post, My apologies if is not. I just wanted to share that I am really impressed with the customer service from OpenBuilds Store. I placed an order yesterday and got the notification today that some of the parts that I needed got back in stock. I am trying to build a C-Beam machine and I had to replace some of the itens with what was available in stock. However, I got some notifications that items were being restocked. Initially I sent an e-mail to customer service to replace some of the parts for the new restocked ones. I sent another e-mail for another order change when I realized that the C-Beam Bundle was back in stock too. In less than an hour I got an answer, my order was refunded and they ordered the new C-Beam Bundle that I asked. They refunded the extra money to my PayPal account and the entire order looks great. I just want to thank you all for the great Customer Service and share how excited I am to put my hands on the C-Beam Machine, Thank you OpenBuilds Team. Great design and Instruction on the C-Beam btw, thank you Mark Carew. Really happy customer here !!
