## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent value
*by G***E on 22 September 2012*

In the absence of a handheld oscillating tube densitometer costing a few thousand more, this device matches my old school hydrometer to .050 points in accuracy.It works very well.

### ⭐⭐⭐⭐ Good product
*by T***R on 2 December 2015*

It was easy to use and did what I expected
