What our customer's say!

"great product", I gave the LK90TV to my non-musician son as a learning tool.

My two musician sons have hogged it since prima luce.

The box does contain the adaptor. It is hidden in the styrofoam packing material.

"I played Moonlight Sonata without a single lesson!", This is an outstanding keyboard. I've never had a piano lesson, yet I was able to play Moonlight Sonata right after taking it out of the box. This keyboard has a feature that lights the keys you are supposed to play about 2 seconds before you are supposed to play them. As a result, you are able to play complicated songs without a single lesson, or reading a single page of sheet music. It's very satisfying. While I am teaching myself to play the piano, I am able to play beautiful and complicated songs. It's a great way to stay motivated.

My keyboard did not come with an adapter either, so you'll have to pick one up seperately.

"No adapter....This was a rip-off", I bought this and took it to another state to give to my grandchildren on Christmas Day. What a disappointment. Grandpa thought there was an adapter "in the box" as advertised so we had the whole day with no adapter and no batteries. I notified Amazon immediately. They sent me another whole keyboard but no adapter again. I will have to think twice about believing anything Amazon has in its ads. There were plenty of other places to get this, maybe I should have gone to a store where they could show me what was in the box before I disappoint my grandkids again.

"Cool keyboard", Got this key board for Christmas for my mom. But she also got me one. There is no ac adapter in the box like item describes only downer. Lots of fun though. My mom got my lk-90 at sam's and she only paid 150 with a stand included..oh and the one from sam's did have the adapter who can figure.

"No adaptor here either", It seems to be a great product, but I searched all over in the manual to find out whether or not the adaptor was included-on Christmas eve which was not much fun. I think it should've been included for the price I paid.
I gave 4 stars because of all the features. I just hope it lasts.
In one day I've already had to buy more batteries.
