Yes, I use EWT on shares and have found it very useful. It gives me context for where in a trend the price is.
Oddly, it's probably most useful for helping to determine where in a pattern or trend the price ISN'T rather than where it is ie I use it to eliminate certain possibilities. For example, if there's been a downtrend on the daily chart and then we have a move up, we can look at the detail of that move up to se whether it's a new impulse wave up (it'll have 5 subwaves) or simply a correction in the downtrend (it'll have 3 waves up).
Also, IMHO, if you use Fibs for your charting then you really ought to have a fairly decent understanding of EWT because Fibs should be drawn to the correct waves; there's no point drawing a Fib from the bottom of wave 1 to the top of a wave 3 for example. This link between Fibs and EWT is down to the basic assumptions Elliott used when setting out on his analysis. Fibs (the "Golden Ratio") automatically follow from those assumptions.
I've read many times before that EWT should only be used on indices or high volume currency pairs, but then I also remember that when I first started posting on III's CV I was told that TA couldn't be used on AIM stocks. In my opinion, all that really matters is that there is sufficient VOLUME to give a good representation of crowd behaviour in the relevant instrument. On that basis, and since Elliott's original goal was to see if there was a pattern to the Dow Jones due to crowd behaviour, if you can use some elements of TA on a share then why can't you use them all? What determines which TA tools can be applied or not?
I'm happy to help explain/teach EWT as I've spent a great deal of time studying it (though I'm far from an expert!) and, as I said earlier, I've found it immensely helpful in my trading. We must always remember, though, that it does carry a great deal of subjectivity to it and there are (nearly) always alternative counts and views.
