Glass bottle is top notch, sprayer is not [SEP] I got these to put water/vinegar mixture in one and alcohol in the other, to use for cleaning and disinfecting purposes, respectively.  I wanted glass, rather than plastic, for these purposes.  The bottles themselves are top notch - heavy duty glass, nice size that is easy to hold yet doesn’t require constant refilling.  There are two included cap tops which are also nice - leak-proof if you want to store something in them that you either don’t need the sprayer for, OR, are transporting them somewhere and want to make sure no spillage.  The sprayer on the other hand, is not so great.  I do like that the sprayer tube is extra long... meaning you can get down to the last few drops.  But it feels cheap overall.  Other problems with the sprayer:  the screw on top fits pretty firmly, but the nozzle does not stay in place - it sort of swivels around.  This gets to be annoying if you are squirting multiple squirts because the nozzle keeps shifting.  The other thing that might be an issue for some is that there are only two settings and they are BOTH mist settings.  It appears that one is a slightly finer mist than the other (barely) but I am not 100% sure that is even the case.  This is not a problem for me because of the purpose I am using them... but wanted to point this out in case it might be a problem for others.  Overall the glass bottles are great but the nozzles need some work.  It also comes with 4 black labels - the labels actually are sort of a thin rubbery material and seem really nice... but what the heck am I going to use to write on BLACK labels?
