Sharp LC-32Q3170U vs Samsung The Sero

Ordered it to replace the remote that came with my LC-40Q3070U TV. It works fine, but it needs two triple A batteries which are not included

what could have been a good television is crippled by the horrible remote, which is further complicated by samsung's poorly conceived choice to us a rf remote instead of the common infrared which eliminates the opportunity to replace it with an aftermarket remote. the cursor jumps all over the place with a single push, continuously scrolling from left to right. it doesn't matter if you push the directional button once or hold it down. very disappointed with purchase
