The test cylinder works as good as any. I like this because it is plastic, I've broken one too many glass ones! The price is right as well.
I had purchased of these for about 10 years now and it has not ever failed me, until last month where I misplaced it and was unable to find it. After a short mourning period for my faithful missing companion, I got on the midwest online store to see if the still carried these after 10 years. I was ecstatically pleased to discover that YES, they still carry this piece of reliable equipment... so I bought 4 more... then I found my original one. But you never know when you need and extra one, so, good purchase none the less. Shipping , as always, spot on!
It is what it is
Economy Hydrometer Test Jar
I received a new plastic test tube after using my old one for several years. This new one cracked in its first usage. It did not fall, it simply cracked. Maybe the quality of plastic has fallen off or it was just a "lemon".
