The oil and vinegar to do not mix precisely as the increments on the dial suggests. Also, the design would be better if the nozzle curved downward, rather than pointing straight out of the bottle. Ergonomically, it's difficult and uncomfortable to use.
I love this new sprayer. It evenly coats my salad or veggies, and I can "dial" in the ratio of oil to vinegar that I prefer. The bottle is large enough that I don't have to refill it often, yet it's compact enough to transport on a picnic.
I purchased 3, one for myself and 2 for gifts. Thankfully, I tried mine and found that it does not spray the oil, thought it might be too thick so I tried spraying water and it didn't work either. I was not allowed to return them and I will not be giving out the gifts either. So, this was money thrown away.
The purchase and shipping experience was good, but those have nothing to do with the product itself. So when you need someone to rate a PRODUCT, please don't ask about shipping. This product, oil/vinegar sprayer does not work properly. It only sprays oil (even though i got both oil and vinegar in the compartments) i tried to adjust it in many ways 50/50, 100%/0, and other options available in between - wouldn't work. Plus it sprays a tiny-tiny squirt out to the dish, the rest of oil is just leaking down the the outter side of the bottle. Super messy, no use. i'm returning mine
