Good and bad always a relative term for each individual. Hence, i would like say the rating in the form of %age of satisfaction -
1. cleaning 98%
2. battery life 60%
3. women hair cleaning 95%
4. price - 100%, i think compared to other brand price and its work efficiancy is 100%.
Note: plz don't buy PHILIPS, PANASONIC & SONY - i bet definitely u'll be in trouble
