Reviews

★★★★★

"Got the olive green and the weight feels balanced and premium. Brought it to a tailgate and it performed. Color is slightly darker than the listing photo but I actually like it. Five stars from me."

"Chose the stainless version and the fabric is surprisingly breathable. It's been my go-to for morning coffee runs. I'm in Boston, MA. Couldn't ask for more at this price."

"Tracking info was accurate the whole way. Compartments keep everything organized. Took it on a road trip last weekend. Took a day longer than estimated to arrive, no big deal. Customer service was helpful when I had a question."

"Picked the gray model and the grip is comfortable for long sessions. It's been my go-to for morning coffee runs. Slightly heavier than expected, still well balanced though. Happy with my purchase."

"Tracking info was accurate the whole way. It's handled my daily dog walks without issue. One minor scuff on the corner, purely cosmetic. Worth the money."

★★★★☆

"Picked the gray model and it heats up fast and evenly. It's been on my nightstand since it arrived. Packaging tape was loose on one end, product was fine. I'm in Indianapolis, IN. Couldn't ask for more at this price."

"Went with the small and the screen is sharp and bright in daylight. Used it during a move and nothing shifted. Instructions could be a bit clearer, but I figured it out. Would recommend."
