For the price, it's hard to get much better than this. Nice warm sounds, well able to go into oscillation when asked, plenty of delay time. The housing is solid and well constructed so it's unlikely that it will ever break. As delay pedals go, it's got the standard features, a tone knob and tap tempo would always be nice but are not realistic expectations on a cheap pedal such as this.
The only gripe I'd have is that this is not an analogue delay pedal as the name suggests. It is actually a digital delay pedal voiced to sound like an analogue one. Nevertheless, you won't go far wrong in buying one of these.
