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:

      If you are looking to buy a BOSS style power supply you probably have a need for a BOSS style power supply. The fact they that this plug is sideways means that you only need to take up one outlet on the power strip and when playing out etc. lets face it you need all available plugs plus an extra power strip. It works and does it's job. I haven't owned the unit long enough to speak to it's durability, but it works and fits securely. Cord itself is medium gauge so should handle use and be run over a few times with the amps. I have found these things usually die when something extreme is done to them like dropping a china cymbal on it or the drummer does something... drummer like. Manufactures can't make them out of titanium and still make them affordable. If it's life or death than be a BoyScout and be prepared with a 9 volt backup plan.

            Pros

            • Ensures Boss pedal compatibility.
            • Long cord for good placement of Tuner on stage.
            • Solid construction

            Cons

            • More expensive but may prove to be worth it

            Best Uses

              Comments about Boss PSA-120S Adapter:

              I play in a local band 25-40 gigs a year. Had the boss tuner for several years with great performance. The original cord shorted out next to the plug. Though I did get it to work for a job in spite of it starting to fail. Went ahead and spent the extra for the Boss cord instead of knock off because of the long cord and knowing it matched the pedal. After receiving it I'm satisfied it's better quality then the cheaper versions. They just have to fail one time during a show to make you wish you'd got the good one.

              There's only one way to use this product - plug it in. The power supply is recommended by Boss. Other power supplies were cheaper online, but I chose to buy the name brand recommended one.

                  Good product, I use it with my Boss Chorus pedal. The longer power cord is very useful and one would think it should be mandatory for all 9V adapters.
