Small, light and value for money, however if you are buying to use with the monitoring software on Linux - Dont! The cd does have a binary app to use however it doesn't recognise the UPS and standard linux utils can't communicate with it

### ⭐⭐⭐⭐⭐ UPS, works
*by A***R on 2 September 2018*

Tested in practice in brief outage (switching off mains for an unconnected reason). Works as required, not much more to say.

### ⭐ Worse than not having a UPS
*by A***R on 29 August 2017*

Bought to keep pump running on aquarium in case of powercut. After the first day of use I discovered it had turned itself off, stayed off, and no longer worked, despite there not having been any powercut. Worse than not having a UPS. Returned it.
