They work great
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!!!

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

Works great with my SM58 wireless set up
Perfect OEM replacement to the power supply that conked out on me. Works great with my Shure SM58 wireless set up. I'm glad it was only an inexpensive power supply rather than shipping it out to the manufacturer which would've cost more just to diagnose.

Fixed my problem
I was having a problem with my wireless mics cutting out and having a generally weak signal. I was about ready to purchase an entirely new set of mics, but decided to try a new power supply. I'm happy to say that it fixed the problem. Apparently the old one was putting out funky voltages. Considering the price of Shure equipment, this power supply is a great deal!

Exactly what was needed
The replacement Shure power supply was consistent with the OEM and works flawlessly. The price was right...I'm glad I purchased two. No matter how careful you are, with the amount of activity with my mobile DJ/Karaoke business, it's just a matter of time before one will break.

The power supply for Shure
This power supply works great and was less expensive then to buy from Shure. Now I can move my wireless mic and not have to remove the power supply from rack to rack.
