VSITOO 4+

This product is poorly designed in so many ways. The main way is that it is tethered to the app, meaning it can’t function without being connected to the app. The problem is that the app is of extremely low quality. For me, it constantly is reconnecting to the mug, resulting in a buzz sound. Every second! If this is what a “smart” mug is, I would rather have my cold dumb mug…

I like the cup a lot. The app is not well thought out. It leaves much to be desired. I too had pairing issues after my power went out. Tried all day to “discover” my device with no avail. Then after looking at all connections and cleaning them I finally saw there was a power button on the bottom of the cup itself. With the app open in device discovery mode…. while holding the peer button down… I tapped “rescan” and wallah! I can now keep my coffee hot again. I should have never had to try and figure that out on my own. I searched all their support sites… texted them in the app… and tried messaging them in the app. NEVER got any response or reply back. This was a gift so I had no way of returning it.

Overall I really love my mug. I knocked off a star because of the app. It will intermittently drop the desired temp slider down to much cooler than I want. I like my coffee hot and from time to time I will look on the app and somehow the slide is anywhere from the lowered to midrange even though I didn’t change it. Feels like a software bug but I’m not sure.
