"Got the travel size and the zipper glides without catching. Took it on a road trip last weekend. Couldn't ask for more at this price."

"The team was responsive when I reached out. Sound is clear without any static. Used it during a move and nothing shifted. One minor scuff on the corner, purely cosmetic. Would recommend."

"Went with the XL and the compartments keep everything organized. I keep it in the car for road trips. Runs a touch small but nothing a size up didn't fix. Happy with my purchase."
