Pretty sweet

easy set up, nice bath tub. the attachment method to the top of the tent could be way better / secure, but works. The system is amazing for what it is. Just be careful with any bottomless shelter if you are camping anywhere with sand or sandy soil. Condensation gathers throughout the night sand sticks to everything and the rest of the time you use it, sand casually rains down on you and everything.
