I have one for putting gas in my boat’s gas tank at a dock from a gas can. Works great for that. I could see using it in non-beer liquid transfers in the brewhouse.
Yeah, that's all I plan to use it for. I wouldn't use it for beer because it looks difficult to position precisely in the vessel, and if you need to restart, it wouldn't be as easy and could end up stirring up sediment. Autosiphon and regular siphon are good on those counts.
