Oh my gosh! This is awesome. I have nerve damage and have a hard time some days to squeeze the shampoo out of the bottle. Times I’ve dropped it and landed on my toes, was frustrated. I saw this and ordered it. I bought some double sided gorilla foam tape and used the silicone glue as my shower has tiles. The tiles are porous and didn’t know if it would stick. I put it in the corner of our shower as it is a very large walk in shower and it is awesome. I primed it as stated in directions. Only took a little longer with conditioner as it is very thick. But once i got it primed i just get in the shower walk over and press the button and i get exactly what i want no problems at all and it’s the best thing ever.
