I have been a piano teacher as well as a vocalist. . I had a treasured spinet piano which I took half way around the world. The problem is that when I returned to the mainland and stayed at an apartment, piano playing was not allowed and I ended up selling it.I have never owned a key board before and did a large amount of research before making this selection. I ruled out keyboards which were known to have keys that didn’t play or really bad sound. It was amazing to me that even well known brands costing triple what this unit did had keys that didn’t work. Others had problems with the keys sticking together. I tried to rule those out also.When I decided on this one I was still unsure. I got the unit today. The whole thing weighed around 20 pounds including the stand. The box was undamaged and arrived ahead of time. The keyboard is very nice. It includes headphones, a microphone, stand and stool. What a deal for the money!. Although it did not say it included an adapter, it has one. It looks very solid with good quality plastic. Very attractive. It was very easy to hook up and play. It has tons of timbres and a transposing feature. It also has a recording and rhythm features. Although I may not use all these features it’s nice to have them available. It’s looks very well built and solid although light weight. Although it did not come with a sustaining pedal it has a sustaining feature. Not sure yet how to use it. It does not have a carrying case but considering all it does have I think it’s a super deal. Another thing I noted in reviews of other products is the music stand was too thin to hold sheet music or books which often fell. This one has a nice music stand which fits the hymnal I am using. Wow! Great buy. I may be updating this later as I start using the tons of features the model has. So far I am very happy the basics are working well!
