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.
I debated whether to buy this or the cordless model which is much more expensive. I went for this one eventually because it is more powerful and more compact, and the water compartment is larger compared to the cordless model, and also the cord never really bothered me before. I am glad I choose this one. It is perfect!
