For $20, does a fantastic noise free job of power supply! Better than expected!!
Despite the fact it is cheap in comparison to the more expensive brands like Voodoo Labs, MXR etc this power supply does a great job, is sturdy enough, and I have not heard any hiss, hum or electrical issues. Seriously, for the $20 mark, you can't go wrong and China is now producing much better quality goods than ever. Don't have to spend 100's (unless you're a pro or gigging a lot) as even the expensive brands aren't actually 'isolated' power supply (for the most part). Anyway, the Caline pedal is powering my 8 pedals (I use Mad Professor, TC Electronic etc) without any electrical interference, hum or problems
