Good quality, but...
These are very well made and good quality but  I was buying them to dispense honey because the bottles from Sam's are too big for me to handle comfortably with arthritic hands.  Unfortunately the sides (thickness of plastic) is too hard to squeeze.  Unless you have strong hands these won't work for anything with a thick viscosity.  The opener was a little stiff but sure it would loosen up with time.  I plan on putting bleach in them to have handy at kitchen and bathroom sinks and figure they will be fine for that.
