I hope this message finds you well. I'm currently exploring options for a 1kW product and would like to gather more information about your pricing. Specifically, I'm interested in understanding the cost per unit, any bulk ordering discounts you might offer, and the expected lead times for delivery. Additionally, if you could provide details on the available specifications and features, it would be greatly appreciated. I am looking to compare different suppliers, so any relevant certifications or warranty information you can share would also be helpful. Looking forward to your prompt response!
