In my house we have been using the v guard inverter for the past two years and its performance has been too good.
This device comes in various designs and colours. The backup capacity is Excellent. It can give a backup of of 6-7 hours in the absence of electrical current.
The battery cells are wet cells and are long lasting , less maintenance is required for the device.
The device is safe and reliable as protective cover is provided to the entire device. The product is very user friendly and is very easy to operate. One manual with instructions are provided to ensure safety.
I feel this inverter is worth the money and one must go for it.
