Cyber Gear Rock 'N Roll Drum Electronic Drums Set

I purchased one of these and it was great. I got it at some place like Rite Aid. I liked it so much it purchased a used one at Amazon. I am retired and learning to play the piano.I use this to help learn rhythm - the beat and quarter beat, etc. Now, is it limited yes, when you hit a note and follow it with an another sound the first sound goes away. ok I understand the electronics. Only one voltage to the speaker. But, for the price - in this case $10.00 it was the best purchase I have made on Amazon. Is it worth $35.00 no,

Might as well have ordered a brick. Arrived, batteries in... power and lights work, but no sound from the speakers or earphone jack at all.
