It's not going to survive a nuclear winter, but feels like it will last with proper care. I don't intend on washing it or taking it apart.
There is a learning curve and some tricks to using it. To prevent the nutes from dropping out of the syringe, you need to "over-draw" the syringe. That is, draw to the desired level while the tip is submerged. Once you draw your nutes in the syringe, back off the nutes and draw air into the syringe. Right now, that seems to be the trick to avoiding nutes escape/spill from the syringe.
