Review: Good power supplies and customer service is the best - Great company. Their customer service has always been top notch. They are located in the US so just a phone call away. Have been professionally installing their stuff for years now and really like the products. Power supplies are always reliable. Just be sure to calculate out your load. They do not like to be overloaded.
Review: LED Driver - END COVERS - Item works fine. I wanted to add a "heads up" regarding the End Covers on the LED driver itself. This is a very straight forward install so I did not review the instructions (at first). When I couldn't get my LED's to light up , I thought the driver was defective. I even tested it with a DVOM and a 12v test light : There seemed to be no power coming out of the 12V end of the driver! Those are NOT terminal screws / connections on the end covers!!!! Those screws are ONLY to fasten on the end covers; and the electrical connections are Under those covers!!! (as shown in the instruction sheet). It sure fooled me!

### ⭐⭐⭐⭐⭐ It actually works with a dimmer!!
*by N***K on October 10, 2019*

Wow an LED driver / power supply that actually dims the LEDs!!! I thought there was something wrong with my LEDs or dimmer as I tried two different PLUSPOE dimmers that did not actually dim anything and also buzzed. This driver actually works, and works well. I am using the 12v/24watt one to drive 8x half moon 12v LED stair lights. I am also using a Leviton 6674 dimmer in the wall. There is no switching noise from this driver, the construction is solid and the dimming is smooth without flicker. Completely worth the higher price than non certified drivers. The only thing that was odd is that it did not come with a power cord. The lack of a power cord was not a big deal as I had one laying around, but I could see it bothering other people. I have a light switch controlling half of a receptacle in low voltage box, so I did need one.
