Do not buy this.
I bought one last time it went up for sale and it worked exactly one time. Whenever it’s been attached for more than a few days and you disengage the suction cups… they never go back to their original conical shape. They stay flat. Thus they are unable to ever regain suction.
This is because the material used to make the suction cups is paper thin and can’t retain its shape.
So, in conclusion. Just avoid at all costs.
Clearly none of you heeded my advice as it has sold out. You fools! FOOOOOLLLLS!
