EZ RED is hideous for accuracy and repeatability. Unacceptable. That kit of roofing tar thick crankcase additive and magic pills for the gas tank will plate new metal on the cylinder walls of my car engine, too. EZ REDs claim is pocus hocus.
A Lexan or pyrex flask skinny and narrow can be used to take several incomplete draws to take a real sample. That way you can lay the hydrometer on it's side and end up with enough electrolyte to work with. The tall skinny cylinder has a very wide base for stability.
The difference in density between 1.200 and 1.285 is not great. To reflect it with an arm would take a jeweled swiss precision mechanism.
I checked then rejected a full factory pallet of "SLEEZE E RED" hydrometers. Having 1.242 batteries read 1.275 and 1.285 batteries read 1.255 is not my BAG
They are made in China and go from final hand fitting of the bulb and tube to the shipping dock without being checked. Save your money for a magic 8 ball fortune telling toy. It will be just as reliable.

Ding Dong. The package arrives. It is torn open and the gizmo is held up for inspection. Then the buyer rushes to the computer to comment.
