I own two of these bottles. One I use with toluene and alcohol and the other with distilled water. They produce a nice fine stream at a great angle that saves the effort to invert the bottle, are a great size for my hand and easy to squeeze until basically the last drop. The cap is easy to screw on and off and seals well to the bottle, but the hole where the straw penetrates the lid is just a close tolerance fit so after several bottles full of fluid they both started leaking at that point when squeezed. It's a good thing the bottle can be used upright: although not a huge problem with the water, it is problematic to have toluene dissolving your nitril gloves. I am considering trying some super glue to seal the straw to the lid as I can see absolutely no reason to make it removable.
