The "Gloria" -prima 5 39th is easy pressure sprayer. However, the valve diaphragm is very fragile and not very resistant to the various spray. With this device, the valve diaphragm held just about 12 applications in two years. Luckily, I found one at Amazon after I did research at the hardware store for the right of the spare part. So you should stock up on time with the flutter valve (valve membrane).
