美国采购需求：爬行动物繁殖箱、变色龙笼、陶瓷灯泡、陶瓷加热器、雨林缸、爬行动物喂食器

I recently purchased a thermometer from your company, and unfortunately, I encountered an issue right out of the package. Despite following all the instructions provided, it just doesn't seem to function at all. I double-checked the battery installation and tried to operate it several times, but it remains completely unresponsive. I'm reaching out to see if you could provide some guidance on how to resolve this issue. Is there a troubleshooting process I could follow, or would it be possible to arrange for a replacement? I appreciate any assistance you can offer, as I was really looking forward to using this product. Thank you!
