Review conclusionRecommendedWith reservations

Only in one review: Current 5 A (12 V 5 A power supply); Power 4.8 W (24 V 200 mA power supply); Test current 5 A (12 V 5 A power supply); Under load 23.6 V (24 V 200 mA power supply); Protection 5.1 A (12 V 5 A power supply); Temperature rise 80 °C (12 V 5 A power supply); Price 2.72 $ (24 V 200 mA power supply).

12 V 5 A power supply: Low ripple and good temperatures at 5 A; synchronous rectification reduces heat, and protection is set close to the rating.

24 V 200 mA power supply: It meets its rated specifications, but has little power headroom and lacks a fuse.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
