Right size, easy to fill
I liked the size of these bottles and the leakproof quality touted by other reviewers.  My only negative would be that these are definitely for thick(er) substances, not water density ones as the plastic is SO squishy that when you squeeze even the slightest amount, the liquid comes out VERY fast.  I put gel hand sanitizer in one of mine and the first squeeze was a quarter size - need to be more careful and squeeze very gently! They have a star opening - not a thin spout - which opens only further the harder you squeeze.
