By and large, I think that the Juice line is a fine series. They are compact and hold the light duty tools of a SAK while giving the user the added feature of some pretty durable pliers. It's a great concept that is working out well for leatherman.
However, they don't work for me. I have a CS4, and the cap lifter does not function. It over extends and will neither lift a cap, open a can, nor even really function as corkscrew assist like it is supposed to. I could send it to Leatherman, but I just never think about it. None of the components lock on the tool, which is no big deal really. However, IMHO, a SAK of similar layers has more walk and talk. Finally, the prices of these little tools are a little high. For me, I feel that getting a light-featured full sized tool like a Fuse or Blast or even a Kick is money better spent at a lower price point.
i will give LM this, the pliers are very, very useful for most tasks that a lighter duty tool might come across. Much more substantial than the squirt line or the small light duty fold out ones on say a Swiss Champ.
All and all, I have given the tool to my wife to beat up and abuse. The knife blade seems to be made out of the same 420HC that the standard LM knife blades are made out of. She likes it. The drivers are stubby, but she doesn't need a deep one, the scissors are hefty and cut very well, saw is pretty good (not up to Vic standards, but it works just fine), and it is a cute blue color so she likes that too
Probably not a bad tool if you like the Squirt line.
