Fantastic device! Noga products are never a bad investment. A few quick notes: the siphon is a bit flimsy. My unit is about 1 foot above my coolant reservoir and is struggling to keep the coolant flow consistent. I raised my bottle to the same height or higher and now it works great. Sprinkler length is approximately 10 inches as advertised. But I found that 10 inches isn't that much to work with. It's long enough to give you good flexibility and a decent range of motion, but not enough to get to every tiny spot you need without moving the entire device. BUT there is good news for that. Noga offers a model with a 19" hose OR a spare 19" hose (Tavers sells it for $40), which is worth it.
