I'm interested in learning more about your product and its compatibility with certain models from a few years back. Specifically, could you confirm if it's suitable for both the earlier and slightly newer versions? I'm looking for clarification on this before moving forward with any potential orders. Additionally, I would appreciate it if you could provide the wholesale pricing details for bulk purchases. Understanding your pricing will help me make an informed decision and potentially streamline a larger order. Looking forward to your prompt response so we can discuss the possibilities further.
