### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent Quality
  

*by A***O on Reviewed in the United States on June 20, 2021*

This landscaping timer is simple to use and built like a tank. Exactly what I was looking for to replace an 18-year-old timer in my front yard. I expect this unit to perform well for many years.Others have noted that this timer is provided with no printed instructions. Neither was mine, but connection and programming are about as simple as they can get. You If you need instructions for a product like this, maybe you should just leave it up to your landscaper.

    Great price, great product
  

*by K***Y on Reviewed in the United States on August 13, 2019*

I recently installed landscape lighting using this transformer and was very pleased with the results. The voltage drop along a 100' run of 9 fence post lights was about 1/2 volt and there is no visible difference in the illumination of the lights from one end to the other. I did run a tee with 4 lights on 1 side and 5 on the other.I used 12/2 wire. I ran 7 pathway lights off of another tap with the same positive results. The product seems very well made for the price.

    Solid transformer for landscape lighting
  

*by S***0 on Reviewed in the United States on June 20, 2019*

The transformer is great weather resistant option for exterior mounting for landscape lights. A couple of notes for people considering purchasing this:The spec sheet inside the door of the transformer states that the transformer can Be fully loaded (100%/300 watts) but the Amazon description warns to only load up to 70%/210watts. With LED lighting, either option should give you a plenty of lighting for a small to medium landscape design.My transformer did not come with any sort of paperwork. Maybe it was overlooked, but it should be mentioned.I do like theoption of the photocell jumper with a knockout directly adjacent to the jumper. It's on the right side and makes for an easy install. I've opted for a smart outlet to pair with my home hub so I can fine tune times, but the photocell option is a simple feature that makes a lot of sense.Lastly, when I put my voltmeter on the terminals, I got a reading lower than stated on 3 of the 4. My readings were 12v, 12v, 13v, and 14v. I did use a fluke T6-1000 which auto ranges and rounds to the nearest full value, but again just so you know what I found on my particular unit.The big question; does it work to light up my lights? Yes. It works. It transforms voltage and distributes the power as I need to get my lights working. Overall I like the unit.
