This pedal appears to be a low-cost take on the Boss Dimension C chorus, at least in appearance. There are no knobs, just 4 buttons that can be used in any combination. The sound is subtle, and a nice alternative to the more common types of chorus. And at this price, it's hard to fault it too much.
But I did notice that the input level affects the results - a pair of fairly hot humbuckers on a Les Paul and the output from a Dreadbox Erebus synth both yielded a noticeable pitch shifting. Lower output single coils on a T-Style guitar worked better, and added a subtle widening to the sound.
With a solid-feeling metal construction and a low price, it's worth a look if you want an out-of-the-ordinary chorus effect. But it's definitely in the budget end of the spectrum.
