I have used mostly the MRF-300 before RF-20. It is a great remote if you have one home theater system or don't use the RF. The RF can't be turned off. If you have two locations, one with the RF receiver and one without, you might have problems. Otherwise identical to the MRF-300. Very good for a place with that only needs one universal remote.

I have 2 of of these to handle both of my A/V setups (since I have some similar devices ex. 2 Panasonic DVD players) I was able to copy one remote to the other. I've lost (or ruined a remote or 2 in my time - so now the first thing I do is add new components to the RF-20)PROS:If you're a tecni-phobe: the basic setup is as easy as much less competent devices. You'll still have the reward of a remote which has a much more powerful signal than most devices and will rarely need to use original remotes. But even the tech-challenged will find it a piece of cake to simply 'teach' a few commands to the RF-20 using the 'LEARN" function. (For those who've never used a 'learning remote' -- this allows you to add special functions that might not come pre-programmed, or those you wish to cusomize.)For geeks: the Macros (which can contain a pause function) are extremely reliable.The Layout of buttons is extremely logical tho some will find this remote a little large and heavy.There are quite a few other features it would take a while to explain - but in general, you can get this remote to do anything with a little customization.Possibly the most useful are: the ability to rename functions on the menu screen (so they can mimic those of the orignal remote), and the ability to add or delete 'pages', functions etc.CONS: The one oversight is the abscence of at least 3 or 4 on/off buttons: To turn devices on or off, you have to return to the main screen, then to the device, back to the main screen, then to the device you wish to use....You can set up macros to work around this - but unless your starting with all devices on or off (or your lucky enuf to have components which have seperate on/off buttons) this will never be reliable. The best solution I've found is to add TV & or Receiver on macros to all other components.MANUAL & SUPPORT: the manual is just about adequate (it suffers primarily from layout flaws - like the need to change pages in the middle of an action. But most of the info IS there, you'll learn it all in time.As far as I can tell, there's NO (phone or email) SUPPORT. So you're on your own. Fortunately, it's really pretty ease to use.SUMMARY:I've tried numerous universal remotes (including the perfectly dreadful Harmony remote), None are perfect, but this is by far the best I've ever used. With a little effort it can do anything (and occasionally more) than your original remote.
