Most suppliers of training equipment are based in manufacturing hubs like China or India, where production costs are lower. Capstone Global, Inc. is based in the United States, which suggests a focus on local compliance, regulatory standards, and possibly higher-priced, premium products. The lack of verification on phone, work email, documents, or account email raises concerns about legitimacy and responsiveness — buyers should request additional proof before placing large orders. While U.S.-based suppliers may offer better support for local regulations or certifications, the absence of verified contact details makes it harder to trust or engage with them confidently. Buyers should verify the company's operations and ask for product samples or references before committing to any purchase.
