I have an older model (~8 years) and one of the wheelbase arms broke off. DXRacer was responsive to my email question and told me which base would work with my model. If you're looking for parts, the links can be found in the FAQ question: "If my chair's warranty has expired and I need to purchase corresponding parts, what should I do?"

This chair was recommended to me in advance by a friend. The chair comes in a very large package and weighs quite a bit, around 25kg. All items are well packaged and most importantly well protected. The scope of delivery includes everything required for assembly. All individual parts, screws, wheels, etc. are included in the scope of delivery, which means there is no need to buy additional tools for assembly.

First off, shipping was extremely fast. I was to assemble it in less than 20 minutes because the instructions were clear, concise, and easy to follow. It feels sturdy and safe. Overall, it has amazing customer service and this chair is great value.
