Hello friends though vguard is one of the trusted products in India in electronics it failed in immersion rod water heaters I was surprised and shocked to at its performance it’s takes more than 20 minutes to heat the water where as a normal heater performs better than this a normal water heater takes less than 15 minutes of time to boil the water but this product takes much time and consumes more electricity I was not satisfied at the product I ordered it from flipkart based on the reviews but they are false so don’t purchase this product
