I bought this regulator after checking all of the reviews. I thought it would probably be the best one with the highest quality for the money. Unfortunately, it quit working after about 2 weeks. I can no longer make any adjustments to the pressure either up or down. No matter which way I turn the adjustment screw, it will not change from 30 pounds per square inch. For the first two weeks I was able to get it to adjust, but I did notice it would not hold the pressure I selected for very long. It kept going from my setting of 45 lb to 60 pounds per square inch. After moving to the second RV park we were camping at, it no longer will adjust. Since I am now outside of my 30-day return period, I will have to deal with the manufacturer to get it repaired or replaced. I don't recommend this particular regulator.
After reading this review, the seller wrote me and apologized for the defective produce. They offered to send a new regulator at no charge. I have received the new regulator and it seems to work just fine. That is what I call customer service. I have revised this rating to reflect their concern, and great customer service. Thanks!
