Honestly, it was not a good model.

I am very pleased and quite happy that I took a shot on this one as opposed to one of the more expensive models!

This device has many features of many expensive models: It supports four devices, it has leaning modes, the buttons can be moved, and has full control for my AV system

Newer models have come out with more bells and whistles (that I just had to own) or the remote that I was using suffered the bane of all remotes - button burnout.

Not as user-friendly as some of the more expensive models, but if you're good with gadgets this is a great remote.

All that being said, the purpose of the above recitation of what occurred is not to criticize the gentleman involved, nor do I need an apology, but it certainly would have been nice to have received some acknowledgement that answering some very legitimate questions and even supplying this technician with the model number, the serial number and the brand of cable box in the original query, sending me a copy of the instruction sheet, without any other comments on the page, to me as a inappropriate response to the question I was asking

I'm not knocking anything off for that, as models like the Logitechs make you connect the remote online (and boy, is that software a pain to use).Simple, fully functional, inexpensive.

so maybe we had an unusual model, we do not know.

Read the instructions about setting a Master Volume and Channel - this will save you time - it allows one button (A-D) to be the Master for Volume changes and Channel changes
