Before I had done me this sprayer, I had a device that was cheaper and has a summer works great. The weed killer has however resolved the seals, so I ordered this brand device. The assembly of the syringe is easy and completed quickly. The filling comes thanks to the large opening very quickly and cleanly by equip. After 5 times will pump has enough pressure inside the syringe, thus allowing easy 2 liters of liquid can be sprayed. The spray jet can be precisely set their own standards. Therefore one must simply turn slightly to the outlet nozzle. I can only recommend to anyone, a few euros more for this syringe to invest before you buy a new cheap every year. A great brand product, what you realize already at the first use. Everything is tight, no drips and no pressure is lost. Class device !!!
