These are realy great suction hooks. I am normally not a big fan of suction anything because they always fall off, but the are great! One big caveat! I bought them specifically for my tiled stand up shower, that has tile like the pic, but the didn’t work at all in there! My tile is slightly textured. Be sure your tile is perfectly smooth or it won’t work. Now, when I put them on the subway tile in the kitchen , awesome! They now hold kitchen utensils by the hood!
