Introducing the "SmartHeater2," a brand new heater for sleep featuring a unique aluminum radiator. Model number: ESH-1100UA No outer box. The package includes the main unit and the instruction manual (warranty has expired). It's a beautiful item, used only a few times. Operation confirmed. To help you better understand the product, I have included official photos from the 1st to 6th images. The 7th image onwards shows the actual product. There are some black spots that may have occurred during storage. Please check the 13th photo and be aware of this. No pets, no smoking. I believe it was stored in a hygienic environment. Many other items are also on sale. Welcome to bulk purchases! I may be able to offer a discount on shipping costs. Please let me know in the comments section. --- Achieves a 5x faster startup speed compared to oil heaters. Equipped with Royal Sleep Mode to support deep sleep and a comfortable awakening.
