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.
We had suction towel rails which were quite difficult to install and kept falling off. Even though there are no instructions, these are very simple to install just by by pressing a lever. To date the suction pads are still firmly fixed to our bathroom tiles. Very pleased with them.
We recently had our bathroom refitted, We needed a rail but I was very apprehensive of buying one that needed holes drilled into the tiles and then find it wasn't in the right place. We found this rail and it's exactly what we wanted. It looks good and the suction is amazing. If we decide we want to move it we release the suctions clips and relocate it. No damage!!
