Perfect, Great value, perfect

Works very well. Excellent build quality. Ease of use and design is good. Able to use as a transfer from one cell to another. I squeeze the top slowly to absorb the material into unit. Extremely sensitive readings with this product which worked great for me. Do not breathe the fumes so this works very well in doing that. Be safe. Wash it up and put unit back into the package it came in. Awesome. Thanks

Easy to read-small-plastic thus tougher than glass hydrometers.

The EZRed hydrometer works as well as a floating bulb hydrometer. Easy to read. No leaks. Works very well and made in the USA--no china manufacture. This hydrometer does require more battery liquid than a small ball hydrometer. Checking the condition of a small battery such as a motorcycle battery could be difficult because of insufficient volume of liquid.

Great hydrometer

This is a great hydrometer. It is well made, easy to read and easy to use. Sure beats the old baster style I used before.

Helpful tool

I found this easy to use to find out more about the condition of my batteries. Now I can compare the difference from a new to an old unusable battery.

Cheap, easy to use battery tester

I use this to check SG off a forklift battery that I'm using in my off-grid solar system.It seems to be working and SG tracks voltage as expected. It's easy to use and does the job. I didn't know how accurate it is as I didn't have anything to compare it to.I have a couple of criticisms, I wish it had numbers marked between fair and good so I don't have to estimate, and I see small cracking around the edges which I know can come from the method used to weld the 2 halves together or if solvent is used to clean it in the manufacturing process, but to be fair, I have also left this under the metal cover of my battery outside, so it has been exposed to the elements and temperature swings below freezing. So far no leaks but even if the long term durability isn't there, it's cheap enough to just buy another one.
