About a month ago, I ordered a brand new Casio digital piano from Amazon. Unfortunately, when the piano arrived five of the keys in the lower end were broken. The sensors still worked because the keys would play, but they did not have the proper«springiness» and made a loud clicking sound when pressed. I called the Casio hotline and they referred me to Mr. E as a licensed warranty repair location. I arrived at Mr. E’s around 3:30 in the afternoon and was greeting by a friendly lady who took down my warranty info. Mr. E himself came out and helped me unload the piano from my car and then I went home. At 6:00 that evening I received a phone call from Mr. E saying that my piano had already been repaired. Luckily, it was a simple matter of dislodged key-weights(he said the piano must have been dropped several feet during shipping). While on the phone, Mr. E even offered to deliver the piano to my place that evening because he was going to be in the area for some other repair business. I doubt my extraordinary 3 hour turn around time is typical for repair jobs, especially if it requires ordering parts, so don’t go expecting that. I highly recommend Mr. E’s Electronics for your electronic instrument repair needs because they were very friendly, did a great job, and made the warranty paperwork painless. Thanks Mr. E!
