I used one of these to make an essential oil fly spray. I was worried about it being able to spray the oil and water mixture but it does so just fine.I also use it to make spray colors for stencil work for my scrap books.Honestly, I am mostly pleased with them, but the spray does not come out evenly. The spray may come out in an irregular stream towards the middle, and the outside is a more of a mist, like it is advertised to be. My colors are very thin, made with rubbing alcohol so they evaporate quickly without warping my paper, so I don’t know if it is TOO thin to get a good mist with this bottle or what. I have a larger, store brand bottle that I keep rubbing alcohol in as well, to kill flying insects, and alcohol comes out in a mist just fine. The color I used to tint the alcohol is thin, glycerin based, (cake decorating colors dabbed in the bottle with a toothpick) and I use very little. When I spray on my stencils I get a gradient look, which looks more interesting, so I don’t mind. The thing that DOES annoy me about it is the stream that sometimes comes out. It makes my paper too wet and the color soaks through the backside, making it difficult to stencil on both sides…Unless I was sure I could find a better quality bottle, I probably would go ahead and buy these again. They work fine around the house. For higher quality, I expect to spend more money, so I am giving these bottles four stars. For what I paid, they are a good deal.Edit to add, a few of them have tried to leak around the spray head. I just make sure to keep them right-side up and the cap on tight so if anything drips, it may be caught in time.
