If you are a studio guy or a hobbyist, this plug makes a lot of sense. While its kind of pricey for what it is and I saw comparable "knock offs" for the price range, it just didn't make sense to risk my $$ ME-70 for a little price difference. And now I know I have MF and Boss to stand behind me stuff.
Its a plug...
This is what scared me a little. I really didn't want to have to buy batteries for my ME-70 and "compatible" adapters scared me so dispite what I read that the quality was poor I bought it anyway. After examining it closely I can say it appears to be made about as well as any other adapter I own, if not better. I have to say I am not a gigging musician; more of a studio guy, so perhaps in a road scenario it doesn't stand up as well but that could be said about anything, really.
There are 2 reasons to get this:
1. Never have to buy batteries again
2. If you use it with the ME-70 (and probably any other pedal), it shuts off the device once you cut power to it. This means you don't have to unplug the input jack. I have it hooked up to a rack mounted "rack oft switches" so I can turn it off with a quick flip. I hated the fact hat I had to plug and unplug the input chord all the time. Again for a gigging musician this is much less of an issue. Chances are you would want the battery advantage for the cordless point.

I generously rated the PSA-120S Power Adapter 2 stars only because of its slim design and its power strip space-saving ability.
These adapters do not last! I have already purchased 4 replacements, and they all have malfunctioned the same way -- the wire develops a short where it comes out of the plastic casing. In fact, one of the two last replacements was defective (in the same way) right out of the box!
Its also worth noting that I have not been out gigging with these adapters and they have never left the basement studio, and so they have not been subjected to any rigorous set-up or breakdown activity and they still malfunction -- I would probably need to buy them by the case if I were out gigging!
In my opinion the PSA-120S are poorly manufactured, they are not dependable, and I would not recommend them to anyone! They're fine while they are operating properly, but unfortunately that's usually not for too long!

      Comments about Boss PSA-120S Adapter:

      I've used a generic 9V Power Supply for my Boss (and other) pedals before, using a daisy chain.

      Lost that one after a gig, and have been using THIS and my EHX adaptors with daisy chains. Using a daisy chain will overcome MOST of the problems encountered when trying to power one pedal alone if it is not a Boss Pedal.

      Final word: If you have Boss Pedals, this adaptor will work for you. If it doesn't work for your Boss Pedals, try it in a daisy chain and it WILL.
      See internet for similar testimonies!

      I use it to power numerous Boss Pedals, a Fender Starcaster Chorus, Dr. Green Hairy Tongue, Danelectro PB&J (don't judge me, I use EHX Reverb and Memory Boy as well), and MXR P-90.

        Get this if you own the Boss Micro BR 80. Although the unit can be operated on battery power, or bus power from your computer, this unit is very useful if you are recording multiple tracks, or using the Boss Micro Br 80 for extended periods.

        Adapter works as described. I use it to power a Boss effects pedal. The plastic doohickey in the middle of the cord makes it hard to wrap the cord into a nice compact loop for storage and transport.

              I'm bad. I didn't notice that this was reverse polarity aka center -, ring +. it does have noise filter in the DC line and upon removing the two screws holding it together it looks like with a little help from my sodering iron i can fix that.

              The PSA-120S AC Adapter lacks quality, workmanship, and endurance! This is the 4th adapter I've purchased, each to replace one which has become defective, and all with the same defect ... the wire shorts out near the plastic casing! It is also worth noting that I've not played out or exposed these adapters to any rigorous activity and they still short out without ever having left the basement studio -- something you may wish to keep in mind before purchasing!

              Is a great product but Boss have to make quality cables for this unit.
