Usage time is about 1 hour, and operation has been confirmed using the TOPPING Professional app. After that, it was stored without being used. Because it was used for a short time, it is recommended for those who are looking for one. Please understand that this is a used item stored at home and inspected by an amateur, so there may be minor oversights. If you are particular about the condition, please consider before purchasing. Instant purchase is OK. Please feel free to comment if you have any questions. Please refer to the following URL for product details. https://musinltd.com/topping-pro/1144.html
