I'm surprised there are not more reviews for this device. Do it anyway thrilled so much that I even write my first on Amazon. After the umpteenth broken Gar *** a syringe, I got sick and was looking for a more solid alternative. At the hardware store, I found nothing, and the 'existential-it-still-the-good-Dinge' shipping it was too expensive. Then I came across this product and ordered a trial basis this and another syringe from the same house. What can I say: Solid, accurate, valuable, no comparison to plastic Gelump the market leader. Then there are the names on the adjustment wheel in German - it feels like an Manufactum product, at a fraction of the price. Now I'm very curious to see if the service life delivers what the appearance promises. In the fall I will store the device from now on in the basement, then I hope to turn a long time. Another tip: half a star would pull me, because the gun was initially leaking. An email to the manufacturer, which was answered very friendly and speedy, but brought the crucial tip: The coupling piece is turned on only hand tight. Pull-resistant with a 18er wrench, then there are no leaks. This was supposed to be from the factory already so, then one thinks.
