The 899 yuan electronic coffee wristband is sold out on multiple platforms, similar electronic coffee wristband products were already on sale 10 years ago.

Recently, the "electronic coffee bracelet" has caused quite a stir on the internet. Blue Whale News reporters found that this bracelet is priced at 899 yuan, but it is currently unavailable on major e-commerce platforms. Blue Whale News reporters consulted multiple customer service agents on various e-commerce platforms, and they all said that the related bracelets are sold out and being restocked. However, it is noteworthy that while the sales are hot with the bracelet being "sold out," the brand behind the bracelet, Shule Leisure, has launched a "disturbance protection function" on social media. In fact, the "electronic coffee bracelet" that has sparked heated discussions among netizens is not a new product that just recently appeared. There have been previous attempts to "optimize" human reactions through microcurrent pulses. The Pavlok bracelet entered the public eye around 2014, with the product's official website stating that the bracelet uses "aversion therapy" to train the brain to associate the discomfort caused by electric pulses with the habits it wants to quit, thus helping to "break" bad habits. From 2014 to 2025, these kinds of "self-discipline tools" seem to have always been seen as a "good idea" by businessmen, but their effectiveness and scientific basis have always been questioned.
