### ⭐⭐⭐⭐⭐ Very happy!

A really well made piece of kit from MXR,compact,light but sturdy.It works really well and is silent in use even with high gain pedals............highly recommended.

### ⭐⭐⭐⭐⭐ Absolutely brilliant and fits under my Pedaltrain really well
*by M***O on 26 February 2024*

I bought this because I heard it fits nicely under a PedalTrain Metro board and it does. So well, in fact, that after I bought the first one, I bought another immediately after so I can power up to 12 pedals. Feels really robust, is really simple to use. I'd never realised that a few of my pedals (e.g. my Boss RV-5) weren't getting enough power. The only downside for me is that the power cord has a bigger plastic bit on it that feels like it's always in the wrong place for my pedal board and that it might get crunched under the weight, but that's up to me to affix it properly in a way that it won't.
