I've used a Koma reel now for a few years and I think they are superb and even more so for the money,the spare spools are a tad expensive but then you get what you pay for,the Koma is a straight foward working mans reel, it's got a great drag system, it's easy to use and fast to change a spool over, the reels have very wide and deep arbors which can take a lot of backing before you load your lines, I use 2 different sizes depending on the size of rod I'm using at the time.
I'd rate the Koma 9.5/10 -- I don't really know why I don't just give it a 10/10
