Excellent hydrometer and much easier to use than the glass tube version. Definitely a great buy!

Whenever possible, I try to buy products made the the USA over foreign imported products. Made in USA keeps Americans working and it usually implies a quality product. I recently purchased an E-Z Red hydrometer for my car battery and also one for my car's coolant. I can't speak for the accuracy because at present I don't have a reference to compare them to, but the build quality is not very impressive on either of the E-Z Red tools. Also, the float on coolant hydrometer tends to stick and I have to shake the tool until I think it is where it is supposed to be. I know how to use these tools, but for someone who is not familiar with their operation they'll have to use Google for instructions because there are none included with either tool. I have a refractometer coming which I plan to use as a reference against the E-Z Red hydrometers. If there is a discrepancy, I will update this review.

Totally DOA. The white disk was frozen in place so no measurements could be made. The top of the rubber tube had a whitish crusty residue that looked like contamination of some sort. A refund was issued. I will stick with my 40 year old hydrometer with the 5 floating balls. They have never gotten stuck.

Does it's job. I had just installed a new solar set-up on my travel trailer with a couple of Trojan batts. We will occasionally dry camp for a week or two and needed to make sure everything was working together. Numbers always matched my meters and showed when I just had a surface charge. When we spent 12 days in the redwoods, with about an hour of clear sun a day, it showed my batts were about dead after 10!
