I don't have any experience with that particular reel. Like Ard mentioned, it is very reminiscent of the Hardy made CFO reels but with a knob more similar to the newest Orvis made CFO's. It's a Hardy, how bad could it be? .
Looking at those specs, 2 3/4 and 3.43oz that's going to be a small and light reel. You'll not get a whole lot of backing on it, which is OK in theory because you'll likely never use it. More backing would add more weight though and that might be a good thing depending on your preference. This one would be too small and light to suit me on a 9wt, but 8 and under would be more appealing.
What size is your #4 rod and what is your budget for a reel?
