Question: Can this remote migrate throughout the house to operate 3 DirecTV units?
Document: It is to be hoped that more mainstream manufacturers recognise that while small, complex remote units are useful there should be more options available for those who are elderly and/or disabled.
Do not buy this remote! It has many flaws.1. This remote will not operate a DISH Network HD Receiver. None of the supplied codes work and the "seek" feature for codes doesn't work either.2. It will only power on/off and raise/lower the volume on a Vizio TV. It will operate the input switch, but it skips terribly, so you might think you've selected the correct input and in a few seconds it will skip ahead.
Four size AA batteries are required, but with good quality ones they should last a while.The main downside is that while the Hy Tek unit can be programed to operate just about any tv, dvd unit, vcr, cable or satellite unit doing so, via special codes, can be a long winded, complex operation, dependent on flipping backwards and forwards through the operating leaflet provided.
This is a great remote. The buttons are nice and large, very easy to use. The remote is also easy to hold.
I  sure do like this remote easy to read .plan to buy another one getting online to read how to use it sure was helpfull
This is just a regular remote that you would buy for less than 10 bucks at Walmart. The only advantage is the large buttons. When you push a button it reacts more slowly than the other remotes that I have.
I bought this item for dad to use, he is 92 years old and has several physical limits. The remote was very easy to setup for his TV and was very easy to show him how to use it.
The buttons were a little hard to push. Also, when we had it set up, we realized that we couldn't change the channels and the volume both on the new remote. We found another one that cost a lot less and worked better.
With electronic equipment such as tvs, DVD players etc, a remote control unit is mandatory: unfortunately there are few mainstream manufacturers who cater for the elderly or disabled whose hands/fingers might be crippled with arthritis or similar afflictions.
My Mom has had one of these for at least 10 years and it worked perfectly until recently when liquid was spilled into it and left. With the large lighted buttons, strong construction and ease of use there was no question as to our replacing it with the same unit. The new one is super. I 100% recommend this remote.
Answer: No
