I've used the mini mojo and actually quite enjoyed it. I did have a couple of concerns though.
440A steel is just not enough for me, at that price...I mean, what you lose in steel you make up for in assisted opening, if that's important to you (and it probably is). I wish they'd make a D2 or at least 440C mini mojo--if they did, I'd be EDCing it right now.
Also, it's been awhile since I've used one, but if I recall correctly, the spring in the lock mechanism is exposed (it's in the blade). This probably isn't a concern, but I guess in my mind it's a little more vulnerable out in the open. On the plus side, it might be easier to keep clean that way.
Other than these minor things, for 65 dollars, you'd be hard pressed to find a better assisted opener in my opinion. I like that it's less than three inches--I mean, a three inch blade you can often get away with in public, but it's more challenging when what you're holding is considered by the unknowing a 3+ inch switchblade. So for assisted opening EDC, I think 2-2.5 inch is most appropriate, which, if I recall correctly, the mini mojo meets.
