I tested two things, and both failed. 1. Yaduo Deep Sleep Pillow, praised to the heavens on Xiaohongshu/Twitter. After using it for a week, almost every morning the pillowcase had blood on it — I checked, and it’s due to breathability + dryness, my nasal mucosa protested directly; individual differences are something marketing will never tell you. 2. OpenClaw also took a spin. The conclusion is that the gap between domestic APIs and overseas APIs is as big as two different products. Plus, with Claude, GPT, and Gemini commercial versions already being sufficient, ordinary people really don’t need to follow the trend and mess with this.
