The one I received is not like the one on the picture, but as they say "specifications can be changed without prior notice". It's wider but also shorter so the overall size is the same. It's extremely lightweight at 53 grams, totally different from the 273 grams transformer I used a couple decades ago. The cable is not the thickest but for home it's adequate, it will not be dragged around, stomped and pulled on like the cords of things that travel by truck from gig to gig.
Some transformers are accused of causing hum in pedals but this one does not make hiss or hum. I tried it on a digital delay that drains a lot of current, a Metal Zone double-stage distortion, and a reverb pedal, it works neatly with all. The plug locks firmly in all but enters all the way only with the TC Electronics reverb, with the Boss pedals it enters 3 or 4 millimeters less deep.
Overall it just works nice and causes no problem at all.
