Agreeed. I also have four kids so I like the idea of an indestructible SUV uke so that they can get familiar with it on long trips. We don’t have those fancy DVD things in our cars and hopefully never will.
I myself have a Flea. I have it tuned to Baritone DGBE. The fact that you can use a Phillips head screwdriver to lock in the tuners is a great feature. Not familiar with the outdoor specific built ukuleles, but I do know the Flea has a flat bottom so no stand is needed.
there's a gigantic thread on swapping tuners on fleas/flukes... in most cases some mod was required, reaming the holes or altering the tuner base plates. do-able for sure, but not an easy drop-in replacement. and then there is the esthetics/cosmetics/look/whatever to consider...
Jerry, can you provide details on those drop-ins?
I took them out of my box of tuners. They're the type that have two screws, one top and one bottom. I had to trim the bottom of one so it would fit above the bottom tuner. I also had to trim them a bit because they were wider than the wood of the headstock. The shaft must be fairly long because the legs of the headstock are fairly wide. The first set I used wasn't very long, so I found a set with longer shafts. You want to have enough shaft to roll up the string.

They are not completely locked in, but they don’t flop like they would if they didn’t have the tension.
