) It looked like it had suffered a lot on its journey
The product came in a plain box without any documentation (is that even legal?) It looked like it had suffered a lot on its journey, it had dents and scratches. The plastic flap that protects access to the contact screws cannot be fully lifted, which makes it hard to fix or loosen the screws and insert or remove wires. Finally, the power supply is not shielded. When I run it in the same room as my computer, the image on the monitor becomes blurry and distorted.However, it does supply enough power for a strip of 300 LEDs, which is what I bought it for.

Good value
A cheap, reasonably well made power supply.My only reservation is the no load output voltage is about 8V. Even a small load (say 2 X 120 ohm resistors) will bring it back down to 5 V.If you are worried that your equipment could be damaged by 8V if it drew no current then I recommend a small permanent load.
