I’d give this idea a million points! It’s clever, useful, and a huge space-saver since you always have it with you. The materials feel premium, and the powder-coated finish looks great.However, the execution still needs some development. My main concern is the 'materialization'—the inside of the bottle has an unwelded seam where I can see bacteria eventually building up. Additionally, the outer sleeve doesn't close properly on one side; even when shut, there’s a gap that looks 'off.' Finally, the air hole on the lid is too large, causing coffee to splash out even when it’s supposed to be closed. This might just be a defect with my specific unit, but it’s worth noting.
