To be fair it is not the best pedal out there, but it is useful when it comes to adjusting some minor settings to a guitar which doesn't really needs it and boosting, however it has very nice definition. Never had any problem, a really nice pedal.
Since the Orange amps Terror line to not have an equalizer (just a tone knob), this is a mainstay on my board. Stays on all the time to dial in the perfect tone. Could be used as a boost as some have mentioned, but it has a very harsh switch (at least mine does) which causes a large pop when you engage and disengage it. Great for the price and for my use! Just started noticing that is is fairly noisy however, it only just started getting bad after about 3 months of use, but its only noticeable when there is silence from your guitar, otherwise it isnt loud enough that you hear it while you play.
