I've been using the Scrubi for two weeks now. Truly love the gadget. Attached nice to my trolley. Now here is what i noticed. It losens quickly and ends up leaking the water. So the sticky item bonding the two plastic parts isn't strong enough. You need to come up with a different way to bond it. Or perhaps finish the scrubi outside layer with another plastic layer so that it doesnt loosen and leak water. I've had to use masking tape to keep it bonded together and still tight.
