I have purchased Guru100 from Bangalore for Rs 1430 on August 2008. Till today from my experience .I would like to mention few points here.
It is really suitable phone who really needs a basic phone. The most noted thing, the battery life. I am an average user, and needs battery charging this cool phone only once in 6 days.
It has a capacity of 500 sms and 500 phone book entries which satisfies any normal user.
One more important point I need to bring everyone attention that it takes less than one and Half hours for complete charge
It is very easy to handy. Keys and display is best in this price range mobiles.
Very decent look and sleek design.
Also it contain a clear loudspeaker for call conference
This is my sincere advice to all who looking for a stable phone that won’t disconnect during important conversation or to present to your child(basic and descent device), please go ahead and buy.Definitely it will fulfill your requirement.
