So, I bought this because, after some discussion with the manufacturer, I was assured that it would handle hot (200F) liquids, which is important to me because I make hot sauce and wanted to automate my bottling a bit (ladle and funnel = lots of waste, very time-consuming), but I needed something that would fill not only a 5oz (150mL) woozy bottle, but also a 1/2 gallon (1750mL) jug for my restaurant clients.I haven't put it to work yet, so I can't speak to the temperature tolerance, but I'm very concerned that they sent me two of the same size nozzles, which have openings that seem to me to be far too big for the tiny necks on a woozy bottle. It'd be nice if they included a finer nozzle for small bottles like this.Granted, they're pitching this for honey, not hot sauce, so I can't complain too loudly - no one puts honey in a small-neck bottle. It's solidly constructed, and the use of weight as a vector for volume is pretty smart. I can't wait to give it a spin in the kitchen to see if the hoses can tolerate hot-fill. I also like the ease of teardown and manageable weight, as I work in a commissary kitchen and storing equipment there costs extra on top of what I pay to cook there.4 stars, would be 5 if they included (or offered separately) a nozzle designed for small-neck bottles. As it is right now, I'll have to use a funnel with my woozy bottles, which is an extra step in calibration and in filling that I'd prefer not to have.I'll update this once I put it through its paces with my actual product next month.
