Review on Watering Refill Applicator with Individual Measurement by Adam Browning

I had liquid medicine prepared for my cat at the pharmacy and the syringes that came with them were terrible so I found what looked like a good deal on different syringes. The problem is that the tip, which should fit snugly into the plastic hole at the top of the medicine bottle, is too small, or more specifically, smaller than the size the hole is designed for. I can't tell which size is "normal", normal size, I know the size difference makes the process a bit more complicated and sometimes confusing.
