Anybody Using ElvUI?

I'm considering changing to ElvUI. I'm told that it is considerably lighter wrt cpu usage than the default Blizzard UI plus the usual plethora of add-ons I like to use.
Does anyone else use ElvUI?
Are there any issues with ISBoxer?

[Couldn't figure out where to put this. Move at will!]

There are no known issues or conflicts with any add-on for World of Warcraft and I know that, at the very least, Vecter has used Elv/TukUI in the past when multiboxing.

The only reason I asked is because I know there are a *lot* of add-ons that won't work with ElvUI. So I was more thinking that maybe that the ISBoxer add-on might have issues with ElvUI. Good to hear that's not true.
