### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    They work great
  

*by A***R on Reviewed in the United States on August 13, 2013*

I got this because our old Shure PS20 power supply started to get torn and required tape to keep it working. I couldn't find any PS20 power supplies but this was one number off so I assumed it was just a newer model. Lucky assumption because it is indeed work well with our wireless microphone receiver.The cables are nice and long if you need them to be. I only need one part of it to be full length for my use and I keep the end that goes into the receiver coiled up. I would say this can reach at the least 10 feet. The transformer piece in the middle is also half the size and much lighter than the original PS20 which is great.I feel like this will last a long time. I would definitely buy another one if I have to in the future.

    Works great

My adapters connection came loose at an event and was the last thing I needed to happen. I taped mine very carefully so I could use it and ordered this one and got it the next day for the wedding I had the next day. Works great and is so much cheaper than ordering from the manufacturer. Thanks for saving me!!!

I used it for a while but it seems to short out very quickly. Like within a few weeks.
