As elsewhere in India, Mumbai Suburb also has its share of Planned(not as unplanned elsewhere) Power Cut Chasms??
No worry ! The Birla Ecogen EPG 800 Easy is the tool that U need to forget, indeed forget, the trauma. The Device is compact, trustworthy (not failing when most needed), as others tend to do, and above all, very affordable.
One needs to just install (done by the Vendor usually), plug in and forget. U will simply notice the device U just installed has taken over whenever there is a power failure.
The battery banks are Robust, leak proof and ecofriendly.They don’t emit foul smell, (remember the ad of Yoga Guru). It occupies an in cognigible slot available in any furniture and can be esthetically accommodated.
I, for one recommend this product, but, as it is collequelly said, "the proof of...is in its.... ", So, if U trust the reviewer then go for one and Experience the difference between, Darkness and illuminated home, Sweltering existance and cool comfort.
Decisision should depend on "putting up with or getting the best".
All the best
