This is a handy gadget that delivers a useful dose of lube where it's needed. It's great for use with any butt plug, especially the larger ones, as putting lube inside helps keep the outside from getting too messy. It's great before anal sex, too, for the same reason.
The tip is rounded and the device is about the thickness of my little finger, so is easy to insert. The length is just right, too. The lube is inserted at a useful depth, without discomfort, and the rings allow one handed use. It seems solid enough to last a while, too.
We've used this with several brands and thicknesses of lube and they all worked fine.
