This slide pool has a lot to offer. Unlike a tube, the rim of this tub has a rubber ring (O-ring?) around it for an airtight seal when the lid is closed. I would choose this lube over a tube of Olympus lube as it lasts a very long time. The lube itself does what it's supposed to. It is soft and spreads evenly. It is compatible with the O-rings on Olympus housings and I also use it for the INON dome port.
