Easy on your hands, doesn't require the force that other brands do to inject meds. Only caution is that you need to puncture bottle stopper prior to inserting draw off. Have had a piece of rubber come through and get stuck in the check valve.

Good product. I find that the O rings wear out and thus one has to replace these. QC Supply sells them, but they are not cheap. As well, I find that the rubber tubing often becomes loose where it inserts into the plastic nipple of the syringe. This cause the vacuum to be broken, resulting in the user to have to re-pump the syringe several times in order for the vial to re-fill. To remedy this, I use ties to "clamp down" on the rubber tubing so that it stays on tight.

We use this product to inject herbicide into invasive trees that are taking over Hawaii's native forests.

Best draw-off syringe i've ever used. Never gets air bubbles in vial, accurate, holds needles well, easy to use. I give 5300 shots in one day and hand isn't sore as with other brands. Dropped it and pigs trampled it: only piece that broke was the needle I had in. Best Value draw-off syringe.

This item was just what I needed! We actually use it for competition BBQ to inject meats.
