Syringe OK, not really good hose

The syringe initially makes a robust impression, acts on the 2nd and 3rd view but rather shaky. This is probably due to the rubber gasket, which is not very stable and not sufficiently thick and puts pressure on the inner wall of the syringe. Considering the syringe so with 100ml completely, there is a risk that the piston too quickly jumps out above or strong shaking back and forth. So you should be cautious.
From hose I had once cut off a small piece, because the syringe was so "carelessly" packed that the approach at the end of the syringe was completely caved in and also no longer allowed back really deformed by pressing and shapes. The tube is quite rigid. A stable soft rubber hose would surely be more appropriate. With mounted hose it is with the mounting very difficult, especially if the liquid is only slightly denser than water. I would not buy this syringe for my purposes, and I have also unfortunately no longer used after two tests.
Since the provider they are shipped without shipping and the price is not too high, it would be more kleinkarriert to resend it.
