A AKRAF 3 Pack 150ml Syringes with 27.6-Inch Tubes, Large Plastic Syringe for Scientific Labs, Nutrient Measuring, Watering, Refilling

I don't want to be too hard on these because I purchased them for an unusual use. My wife broke her jaw and has to eat everything through a straw. After a while trying to suck everything through a straw can be difficult, so I purchased these to use as a way of getting blended food fed to her. Works pretty well but after a single use they become very hard to push and the plunger becomes extremely hard to pull out. In fairness, the quality of the syringes is pretty good.

I use these for reverse bleeding my brakes. They work well for that.

It worked well to fill fluids in a transfer case and differentials. I used a new syringe for each fluid to avoid cross-contamination. The syringe makes the process clean and accurate. It may not work well to suck fluid, only to fill.

I like this particular size for my applications. I use this product to measure smaller amounts of herbicides and pesticides for quart size spray bottles. Accuracy is not necessary for my needs. Close is good enough for my needs. I will not be using this product for animals nor people. Syringes will be labeled for their intended use.

My use is to remove automotive fluids in measured amounts. I use one for motor oils, one for brake fluids and one for other fluids. This does not cross contaminate the fluids. The product works best with thin fluids rather than thicker fluids found in differentials. It also is great for removing\adding fluids out-of-position in hard to reach places. No quality or use issues.
