The installation of this shower cursor is super simple, there is even no need to dismantle the shower bar, which greatly facilitates the task. Once installed, this cursor appears solid. There is a lock knob to lock the cursor to the right height. The small rubber part that clamps the shower bar to avoid damaging the bar. The pommel is well maintained and does not move by itself under the weight of water. I am very pleased with this purchase and I highly recommend it.
