Thank you for your support of Psvane. No matter where you purchase from, you are supporting our brand. In fact, our official warranty policy is consistent, which is to offer a 24-month free replacement. Each distributor may provide different commitments to customers based on their own conditions. The difference is that Amazon is currently managed by our team, and the products are from the latest batch that has just been stocked. We can offer very prompt technical support and service.
Regarding your second question, if you order from us and encounter any issues within 24 months, you can get a free replacement tube from us.
For your third question, yes, you can directly send an email to this address.
