I'm interested in your top-of-the-line heart rate monitor. Could you provide more details about its features, pricing, and any available bulk purchase options? It's crucial for us to understand if the device can seamlessly sync with a mobile app. Also, is the app you offer customizable, or would we have the flexibility to develop our own app to complement the heart rate monitor? Furthermore, I'd appreciate it if you could clarify the warranty and guarantee terms associated with your product. Are there options for extended warranties or support services post-purchase? This information will help us evaluate how your offering aligns with our requirements and ensure we make an informed decision. Looking forward to your detailed response!
