The Squirt series are really nice keychain multi-tools. It is true that they do get beat up, but to some, that battle look is endearing and adds only character. In the old series, you have 3 choices, pliers, Wire stripper, and scissors. Thankfully, the naming convention makes a lot of sense (P = pliers, S = scissors, E = Electrical?). The E4 and S4 come with removable tweezers. They are ok, but are not in the same class as those found on Victorinox knives. So it all depends on what main use you will want one for. Most go with the scissors as the pliers are a bit on the small side...but then, it is a small tool.
With the advent of the new Squirt series, the PS4, and ES4 (personally, I think they should have changed the 4 to a 5 or something as the visuals are a big departure from the older series). These two new tools now carry a small pair of scissors much like the Swiss knives. The finish and shape of the tool is now very different. You now have a grittier textured tool for better grip, and the handles are slightly different supposedly to allow the user to figure out which tools are where without having to look at it. I do not know how the finish will hold up after long term use. Also, the old series are now discontinued, but there are so many out there, you won't see any less stock for years to come. I am also sort of sad to see the S4 go the way of the Dodo. The small scissors in the PS4 and ES4 is no substitute of the larger and nicer pair found in the S4. Guess that will only guarantee that the Micra will be around forever. Likewise, they did without the removable tweezers in the newer Squirts. To some, they were little used and mostly useless, but to others, their inclusion was a nice touch.
So go for one, you have 5 choices. I don’t think you will regret it, or go for the Micra…but the Micra is not a perfect tool either.
