Not bought on Amazon. There are 5 Ltr segment (30 - 40). About 4 good manufacturers and that includes Gloria. My Device older but the same type I have been operating about 10 years. Previously I had about 20 years, a different brand also very good. All have in common they have a pressure relief valve which operates at sufficient pressure or auslöst.Dann is reached the optimum injection pressure. So Not looking manometer. What is also unnecessary, my opinion. Now to the syringe part. For 30 years the syringe part has remained the same, the spray nozzles. If something is leaking but it can easily ersetzen.Habe equal dazugekauft a telescopic extension. Because the originals is just too short. The seals are among the sprayers compatible. Either the manufacturer buy fits then sure. I buy in a garden accessory dealers in your area. Lots of seals. Then there are costs of max 1.00, without fuel costs (car).
