Very easy to set up.  Blower takes 1-2 minutes to blow it up.  Just make sure the yellow hose isn’t kinked at the bottom.  My son and I go down this slide together.  He is 3, and it’s almost too big for him (but we should get 3 summers use out of it). I’m approx 170# and 5’5” and I can go down it just fine.  My only suggestion is to purchase a 5x6 piece of foam to go underneath the pool area for a softer landing.  Set up is extremely easy.  I did it myself while my husband picked up our son from daycare.  
It deflated in about 4 minutes, and there is a plug at the very bottom of the pool to drain the water.   Overall 5 STARS :)
