### ⭐⭐⭐⭐⭐ East to fit
*by C***N on 10 November 2023*

Used to keep an eye on a leisure battery, does what it says on the tin....... Happy..... 😊

### ⭐⭐⭐⭐⭐ useful product
*by D***P on 5 May 2020*

Very good value for monitoring battery level. The unit is clearly designed for panel mounting but can easily be made into a stand alone unit. Am using it to check the level of charge on a 12V solar power system and it is ideal to give an easy overview of battery condition. Was considering building my own monitor but this was so cheap that it wasn't worth the effort.
