A smart "Speaker" that doesn't contain a speaker. [Follow Up]
Hey Marshall, First we apologize for misleading you with our title 'smart speaker' , indeed, it doesn't contain a speaker inside, it has to be used together with our 'ESP32 core Basic' , we provide the audio develop platform so you can program it as a smart speaker (power the speaker of 'Basic core' . For people who familiar with our product category and system, they'll understand immediately that the 'Base' and 'Module' can't be used without our 'core' controllers. But new users might get confused, so thanks for your suggestions we'll change our title and descriptions. For the defective issues/quality issues, i'm afraid you have to ask the amazon store which you bought the products for replacement/return. In the future, you can also buy directly at official store, we provide technical support, after sales service, return/replacement policy. Our sales people will contact you directly and get you a gift for your genuine feedbacks to help us improving our products.
