Promising review: "This fun gadget has a permanent spot on my bar counter! The unboxing experience was luxurious, the setup was beyond easy, and connecting to Bluetooth for a perfect drink every time is simply amazing! I love the app, especially loading 'my bar' using the scanning feature and then creating the best drinks with ingredients readily on hand. Also lets me scroll to find my favorite drinks or explore new recipes and cocktails. No need for a jigger or stirrer = fewer tools to clean as the coaster signals when to stop pouring. This will be my go-to for cocktail prep on a chill night or when hosting friends and family." —M. Azcona
