Customers like the size of the kitchen product. They say it is relatively small, compact, and easy to use. They also find the small size very attractive and practical.

5 Stars
Essential for testing FLA electrolyte
Easy way to measure electrolyte specific gravity. Make sure you get enough electrolyte for the float to move freely, or you'll get an artificially low reading. This battery was charged to 12.3V.
