Definitely Lexicon quality. There's a natural warmth and randominess with the reverbs. Resonator is useful sometimes and well done, but I don't like the flanger. I just can't get heavy enough flange no matter how I set the parameters. I'd trust this machine to handle the job even under heavy conditions.
Operating systems seems to be reliable.
I'll pass this one. Have no experience. I'd recommend this to anyone who is looking for good reverb for decent prize. Editing patches is limited, but easily enough to create sounds far different from what they originated from. This is not indicative of anything, as you can find dogs from every manufacturer, to my experience.
