Mini UPS Backup power supply 10400MAH - Wifi Router Ups

I ordered two of these: Mini UPS Backup power supply 10400MAH - Wifi Router Ups. The price was good and stock was available. I paid online and chose the option to collect as I did not have time to wait for delivery. To date still happy with the purchase, the UPS units are doing what they are supposed to. They gave a 6 month warrantee, so I will monitor the UPS units closely.
