Bestest invertor till date I buy.charging is so fast and backup also good.it also have indicator that show when the bettery need to be maintained.firstly I want to buy a luminous invertor.but some says that maintance of luminous is too costlier.than I prefer to buy microtek.but I done a mistake that I did not buy a pure shine invertor.but it’s ok for me.working good.I give it 4 out of 5.becoze it is not pureshine.but I advice you everyone.who read my review before buy a invertor.go for pure shine invertor.best of luck
