It is just a bit bigger than a normal pedal from Boss or Behringer. Very solid with big knobs, adjustable by foot. This pedal has a clear nice tone, not to warm, not to cold.
The only feature that it is lacking here is tap button, but you can obtain the same thing through knobs, by tweaking the optimum delay time and number of repeats. But the strong point of this pedal is switch for musical measures: 1/16, 1/8, 3/8. The last one, 3/8 is awesome, allowing to play with echoes intertwined by your original notes. I doubt you can buy anything better for this price.
I can't find any cons, except the lack of tap button, I just love it.
