Easy installation with a strong vacuum suction cup, adjustable angle shower head. I used it for 2-3 days. I am selling it because the size didn't fit. I will also include the attached sticker, but the suction power is really amazing, so if you attach it to a flat surface, the suction cup alone is sufficient. - Suction cup type: Strong vacuum suction cup adopted - Installation method: Easy installation with double-sided tape - Angle adjustment: Adjustable up and down 20 degrees The following is from the official website. It really doesn't fall off. Super strong fixation for secure hold. It has a glossy metallic silver finish that looks great and a slightly rounded, modern design. It creates a luxurious bathroom wherever you put it. It's simple, so it blends in well and can be installed without looking out of place, as if it were originally there. With the lever-type vacuum suction cup, simply press it against the wall and turn the lever to firmly adhere. It can securely hold the shower head. The angle-adjustable shower hook can be adjusted up and down by approximately 20°, so you can take a shower at your preferred angle. You can freely move it to the right place and adjust the height. Because it can be reinstalled, you can always comfortably use your favorite shower head. You can easily install a sturdy shower stand without making holes or scratches in the wall, and without tools or force. Of course, even women can easily install it.
