I do not, I think. But I had no problems with them and was using it for at least 3 years. It is made of plastic and does not create super pressure. It is small, about 20 ounces or less. You can set dispersion amount. It has a dial. You can set how fast it will mix (suck) the soap or anything you spray with. I can not carry big sprayer. That is my best option.
