## Customer Reviews

### ⭐⭐⭐⭐⭐ Bueno
*by P***A on August 5, 2024*

Funciona bien

### ⭐⭐⭐⭐⭐ Good supply
*by I***T on May 13, 2014*

I saw some complaints about this power supply. It works fine for me. This isn't meant to be a bench power supply. It provides approximately 9V. My application has an on board voltage regulator so if the output has ripple it really doesn't matter. Most applications use an on board regulator. The fact that the center pin is positive is a non issue since with the exception of Radio Shack products I have yet to see anything that doesn't use a center positive. I would recommend this product.

### ⭐⭐⭐⭐⭐ It Works
*by P***T on December 27, 2012*

I haven't checked the voltage level, or hooked it up to an oscilloscope to check for spikes and ripple, so I can't say much about the quality of the power, and 650ma will not power an LCD shield, but when I powered my Arduino Uno with it it worked fine.I have only used it for a few hours so I can't say much about reliability, except to repeat that so far it works fine.So far as far as I can tell, it works perfectly.
