Has any one used this portable shower?
 

I was cruising the local Bass Pro Shops yesterday and I saw this shower in the camping department called RinseKit. It looks pretty cool and they claim that it doesn't require pumps or batteries to pressurize it.I'm very hard on my stuff so I wanted to ask before I purchase one if anybody has used this thing on here?

Down below I will add the website down below so y'all can check it out.
