Products in the top-left offer the best value (high score, low price).

Professional reviewers praise the Dioche for its clear 3.5-inch display, stable fit, and short latency, positioning it as a solid affordable option for basic peephole upgrades. However, they criticize the absence of night vision and the restrictive 15-second video limit as key shortcomings.
Everyday users commonly praise the easy installation, wide 120-degree view for better coverage, and clear daytime image quality, often calling it a 'game-changer' for apartments with thin doors. Recurring complaints include the lack of night vision leading to poor low-light performance, frequent battery changes due to energy-saving auto-off, and the short 15-second preview forcing repeated button presses.
