Review on 🔧 Adjustable Plumbing Pressure Regulator by AECOJOY by John Mejia

Got this for my 32ft RV. The instruction was only one page and ended in the middle of a sentence. As there is no contact information on the page I received, not even the manufacturer's name, and nothing on the packaging other than the name "AECOJOY", there is no warranty description and I'm not sure who to contact should contact for service or repair. Questions. Additionally, the instructions suggest orienting the device "so that the gauge is in a vertical position with the rubber stopper on top" to "prevent oil from leaking to the outside." However, the diagram shows the device installed upside down, going straight down from the faucet with the rubber stopper at the bottom. Another directive states that the regulator should not be connected to the faucet via adapters, so there is no way to add an angle to the faucet to properly orient the unit, right side up, without violating another directive . It seems well built to me but due to poor instructions I'm sending it back.
