Review: Excellent replacement for my computer speaker - this was just what i was looking for. unto those who wish to do the same you need some soldering skill. But if you have the will and youtube on your side nothing is gonna stop you. I needed to bend the pins just a little bit to fit it on the pcb board of the speaker but it worked great thanks!!

### ⭐⭐⭐⭐⭐ Perfect fix for Cambridge Audio 2.1 system remote
*by B***N on October 21, 2015*

Fixed my cambridge audio 2.1 wired remote with this little guy. De soldering and soldering was easy and it's the perfect size.

### ⭐⭐⭐⭐ Fixed audio amplifier
*by S***S on February 14, 2016*

Used this as a replacement to a Delta pot on an amplifier (Dayton Audio T-amp). This part is almost a perfect fit, but doesn't have quite the same length leads so I had to solder it to the PCB surface. No popping on turn on and no scratching when rotating the pot after about one month of use. Hope it holds up over time.
