The device is new, I just tried it to see if it works. Fast imagination for store owners. For every project that sells something liquid, it makes the task quick. Important for every merchant. Contact (phone number appears when you press the contact button). The price is non-negotiable, final price 1000. Pickup from home. Reason for selling: I have another one. There are not many requests, I have to sell it. Don't undervalue the price, the last price is 1000. It cost me 1500 with shipping from AliExpress.
