To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
It would be better if there was a timer . and also an ON & OFF switch . The current brand we have is Roman , it was my mistake that I didnt scrutiny the switch etc. Most of the time we heat up our food from the fridge, so it would be convenient if we can put the timer on for five or 10 mins, depending on the food quantity. My preference any many of my friends say it is too small, if the size & height is slightly higher that will be excellent.
