I own a Tilt but I got it for only £99. I want another but am not willing to pay over £130. The Tilt is slick and has no real competition. I use it with a Raspberry Pi so can access over the internet and am not tying up a phone. I like almost everything about it. I add it to the fermenter after a couple of days to avoid the Krausen Krust. As sais above the SG can bounce around during vigorous fermentation. But this settles down quickly. I also love the temperature monitoring. I recently bought an Inkbird to regulate a waterbath for my FVs and demijohns. The temp of these is often two degrees warmer or cooler than the waterbath temperature. So the Tilt allows better control of wort or must during the phases of fermentation from rapid to slow - and I adjust the Inkbird accordingly. My latest WOW took two weeks to reach 1.000 but I can see that is is still dropping - one point a day, so I hope it gets to 0.995 eventually.
