"Customer service replied within a few hours. The color matched the listing exactly. Took it on a road trip last weekend. Slightly heavier than expected, still well balanced though. Five stars from me."

"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."

"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."

"Got the charcoal one and the weight feels balanced and premium. Took it to the lake house for the weekend. The box was a little beat up but the item inside was perfect. Shipping was quick and the item delivered."

"Got the white finish and setup took me less than five minutes. Brought it to a tailgate and it performed. Took a day longer than estimated to arrive, no big deal. I'm in Kansas City, MO. Solid deal, no regrets."
