I have 2 regular Tilts (not the mini and not the pro). I did end up using one for a batch of DB. I used a hydrometer for the starting SG, but the Tilt allowed me to monitor progress and temp. It did get stuck on the fruit bag once so I nudged it back into the must when I saw the SG seemed to be stuck.
I love my Tilts! If you get more than one, be aware that they need to be different colors. Also, the default is to record every 15 minutes but I changed that to 30 minutes. I ferment in a bucket, and I keep an old iPad in the same room, for the Tilt to report the info. If you ferment in a metal tank, make sure the Tilt you get can communicate via Bluetooth through the tank material. I know the Pro is supposed to work with metal tanks but I am not sure about the mini.
