I'm currently exploring various electronic access control systems suitable for both residential and commercial use. I'm particularly interested in your smart lock solutions and would like to evaluate their performance firsthand. If possible, could you send me a free sample, including any necessary keys or software? This would greatly help in determining their suitability for my applications. I'm more than willing to provide any additional information you might need regarding my company or projects. Also, I can cover reasonable shipping expenses if required. Looking forward to your prompt response, as I'm eager to assess your products for potential collaboration.
