Rated 3.5 out of 5 by 2 reviewers.
Rated 2 out of 5 by Quality Control is questionable Bought this to replace a previously burnt out power supply. I bought two and first one lasted a week. The second one is on 4 weeks and still running. Hopefully it holds out for a couple of seasons September 2, 2014
Rated 5 out of 5 by Had to mod, but works great! I used this power supply on my ESP-6TM Rain Bird controller. Unfortunately there was no connector to plug it in. The controller needed two bare wires. I just used wirecutters to cut off the connector and strip the wires. Since the transformer output is AC, there was no worry about swapping the leads. It's been working great for two months.
