We are going to buy a little PP for the pup. Mom dad and kid will all use it sometime or another I'm sure, but a major usage will be my 3 yr old instead of rest area bathrooms. As I'm trying to scrub a crusty And wet toilet with baby wipes he's doing his best to touch every surface and subsequently rub his eyes and put hands in mouth. Then back in the car hes literally licking the bottoms of his shoes. I MEAN COME ON KID!! So aside from pup duty (lol) I'm going to turn the mini van into his personal throne room whilst on the road. What the best PPs on the market today? Worst? Features to look for or avoid? Looks like about $100 is the general range. Seen one at $12... um, prolly not. Seen some at $400+... ahh, yeah no too. What say you?
