Pros: Durability, Ease of Use, Effectiveness, Overall Quality
Absolutely worth it!
I bought this for my best friend because his old Lansky graduated set has been used to the point where all of his stones were concave and beyond use. When I found that out, I had to rectify the situation because he has some really nice blades and can't take care of them properly. I own this stone in the 8" long version and it serves my every sharpening need. I make knives as a hobby and when my grinder crapped the bed I even finished a tool steel Tanto I had been working on on one of these stones all the way to zero ground. So, when my buddy's birthday came around, guess what he got. For the price, for the size and even for the weight you cannot go wrong. Toss this thing in your backpack when you are out camping or in the bush and you won't have to worry about using a tiny field stone to put an edge on your awesome 60 HRC blade. It ceases to be an issue.
