Terrific sound quality
This keyboard has little to envy from professional models. When it comes to piano and basic rhythms, you can go a long way. I bought this one as I was abroad and wanted a cheap keyboard that I can leave at my in-laws for occasional gigs, and it really did the trick, including when connected to a professional sound system. I might not use this for my paying gigs (except if it's mostly piano, as opposed to rhythmic pieces), as it does not have all the registration capabilities as the Tyros, but considering it costs 10% of the Tyros' price, it's well worth it. Plus it's super light, I could litterally lift it with a single finger!
