I like these because they are dice. Reasons are twofold. 1) They'll go in my bag of dice quite easily--they fit right in. 2) They seem like they might hold up a lot better over the years. Why should I care? Well, besides the obvious value in long-term durability I do not want to think about trying to track down "Ikorka Ability Counters" a decade from now. (I mean--they're hard to find right now.) So, I'm quite happy to pay a bit more for this solution because it basically means I won't have to replace any of them later unless I lose them which I won't. GREAT.
The dice are a bit more expensive (for sure) and they're made-to-order so I'm waiting a bit for them. Even then, I honestly felt like these were frankly the only acceptable solution on the market to this particular problem. Everything else I look at seems like it would be a downgrade to me. Sorry if this wasn't the feedback you were looking for when you posted this but it is the truth. Hope it helps. Good luck with these they do look great!
