Reviews
"Bought the starter kit and it fits true to size with no surprises. Used it at the desk for video calls all month. Packaging tape was loose on one end, product was fine. I'm in New Orleans, LA. Would buy again."

"Went with the medium size and the cushioning is supportive after hours. It keeps up with my home office setup. I'm in Oklahoma City, OK. Would recommend."

"Ordered the refurbished unit and the battery easily lasts a full day of use. I've been using it daily for about two weeks now. Would buy again."

"Order processed quicker than the estimate. Cushioning is supportive after hours. Carried it through a busy work week. Slightly heavier than expected, still well balanced though. I'm in Nashville, TN. Happy with my purchase."
"Ordered two in different colors and the weight feels balanced and premium. It's handled my daily dog walks without issue. Took a minute to snap together, fits great now. I'm in Oklahoma City, OK. Solid deal, no regrets."
