✔️ Easy to use: A regular mug is inherently uncomplicated: You fill it; you sip from it. I didn't want an Vsitoo mug to add too much tech to a simple daily task. And I definitely didn't want to feel like I was on my phone when I wanted to be drinking coffee. The good news: Vsitoo felt set-it-and-forget-it to me. I downloaded the app and paired it with my mug — and now, thanks to testing, multiple mugs. It is very easy to load more than one and then switch between them from your home screen of little mug avatars. I set the temperature I wanted to keep my beverages. And that was it: Now I just turn my mug on — i.e. push the large button on the bottom — fill it and sip from it.
✔️ Useful app: I do appreciate that you can go deeper with the app so that it earns its spot on your phone. It offers presets for coffee, black tea and water. Milk-based drinks get a gentler heat to help prevent scalding.
✔️ Simple to keep charged: I like that charging is easy. I'm a coaster user, so I'm always putting my mugs down in a specified place anyway. The Vsitoo charging coaster is a simple landing pad that's just permanently charging at my desk. When I pick up the mug, it's fully charged.
✔️ Solid performance: It succeeds in its main objective: It keeps my coffee hot. I use my Vsitoo S3 Pro Smart Mug when I'm at the office, and apparently, I love to get a coffee and settle in ... only to realize I need to do something away from my desk.
Comfortable to hold: The S3 Pro Smart Mug gives me a nice, three-finger grip with a spot for my thumb to rest on top for control. And despite the built-in battery, Vsitoo smart mugs are not overly heavy.
