This is in the family of many of their remotes that use a 'Fuji NP60' battery pack. Easily obtainable, but the run time is ridiculously short. As little as three days, more like two until you have to recharge it.
I have the MX980 which is a somewhat older remote that uses the same pack. if that isn't a problem, out of the two, for a cost difference, I would go with the older model if which there should be plenty available on eBay.
Have stated that, I assume you understand the biggest negative with the URC marketing/sales policy is they are meant to be sold thru 'dealers' and inflated price that would/should include the 'dealer' do the programming (of course adding to the purchase price). Something I whole hearty disagree with. The software is only available thru dealers (for the most part), but most/many will not provide that to you. But, if you search enough, there are other sources that the program can be had.
There is also a older, less fancy remote which, as far as I'm concerned is a better buy based on cost and especially ease of programming. The MX900
. It doesn't have the overly fancy display (it's low resolution, dot matrix). That uses a dedicated program for that remote, but it can also use their 'one size fits all' CCP which is a advanced program that is not
user friendly. The biggest plus is it uses common AAA cells either alkaline or rechargeable NiMh/NiCD that last over a week w/o recharging (outside the remote). I kept a spare set of cells charged to swap out when I used my MX900.
As far as Harmony which is popular here, due to the program being available to the user, programming that is done thru their web site which I'm against. One shouldn't have to connect to the Internet to just program a remote. Talk about 'phoning home'.
I guess it's based on if you want to pay someone to program a remote for you, or do it yourself. There are pros & cons either way.
