4oz/120ml Squeeze Bottles Wide Mouth Plastic Bottles with Lids, Graduated Food Grade PP Sample Containers for Water Sample Lab Reagent Liquid Medicine Storage (Clear, 4 Pcs)

Seems maybe a bit less sturdy than a typical nalgene bottle, but the price is much less and the bottle works well. Unless you are super abusive with water bottles, I think this product is a good value.

Bought these for mouthwash when traveling. I put it in my check bag in a ziplock. It leaked a very tiny amount but much better than the mouthwash bottle.

Works perfect for my need

Perfect for measuring

Okay

Excellent for storage

I use A2 milk, but my local store only carries it in half gallons. These little bottles are perfect for freezing small portions I can defrost when needed. These little bottles came as promised, and described. They are not something I would entrust to the dishwasher, but they are easy enough to clean with a small bottle brush. I'm happy with my purchase.

Light weight leak-free multi-use bottles...I use these to measure out and mix motor oils and 2-stroke oils.I did check for accuracy of the marked gradient lines and they are spot on.I gave it 3 stars because it is sold as a 1000mL bottles, but only marked to 800mL. 1000mL will fit in the bottles but it's just shy of the top of the bottle..I made a 1000mL mark on the cap threads with a sharpie, which didn't last long.If you're going to sell a 1000mL bottle then at least mark it al the way to 1000mL
