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 have always respected GROHE till today. This hand shower clicks with all my expectations except it does not connect to the hose that previously had a Grohe hand shower. As wild as it seems, grohe has devised their own new thread standard and to use this device you need to buy a Grohe shower hose which might cost more than you expect.
