Works.
This worked really really well. The first time I used it, but it is extremely fragile. You have to pee careful because I broke it. Just trying to clean it out, but it works. Excellent it did its job. You just have to be extremely delicate with it. I used it for my forklift battery.

it worked perfect
I was able to find out which battery was bad in my golf cart and I replaced it. It worked perfect.

Works well but I would prefer a longer tube for inserting into the battery
Works but would be better if it had a longer tube for inserting into the battery. My battery bank has large flooded lead acid batteries and a longer tube would make it easier to use.

Works as it should.

No tip!
Mine showed up without the "tip". It's the part that allows the user to reach inside the battery itself to access the battery acid inside. It is 100% useless without it! The plug for the intake side and the flexible tube that attaches to it are not with the item.
