It is not user friendly. Its weight is very high, I can not take it from one place to another alone. It gives me light for 1-1.5 hour after that its battery is low. It disturbs the power line. Its durability is low . company give u guarantee for 1 year but it is not working properly in mid of year and shopkeeper gives not the service properly so all in cases it gives you only problem and waste of money. Mostly the inverter name "Exide" name is so famous but the Exide Solar Hybrid 850Va Home UPS Inverter is so bad. Dont buy it and dont waste your money. Its service is so bad.
