Good luck finding one for $100.
As to your question, they sound good, play easy, are very durable and made in America by people getting a living wage.
In addition to specifically what Icelander53 said here, and the pros that others have mentioned, for me, the A#1 most important feature is the intonation (and in this price range). The intonation on both my Flea and Fluke is very
very good, not perfect, but the best out of my collection.
I do not think that PERFECT intonation on every single fret is even possible on an instrument shorter than about 24" due to the laws of physics.
Some folks do not have the 'ear' or hearing perception for poor intonation and quite frankly, they are better off (bless them - ignorance is bliss).
I simply cannot play (nor listen to) any instrument with poor intonation - it makes me cringe and no longer sounds musical to me when the intonation is far off.
It was not until I got my concert Flea last November 2013 and tenor Fluke in February 2014 that I knew what good intonation was, as in what it SOUNDED like in my own hands.
At the time, I took a leap on the Flea, but the BUILD QUALITY is simply over the top, and fit and finish is impeccable, so after seeing this, I was sold for the Fluke without any hesitation.
For me, the price seems a bit high for all NEW ukes as well, especially if you add the upgrades for anything from Magic Fluke Company, but quality instruments made with care cost more than those made poorly. You actually DO get what you paid for with a Fluke or Flea.
Time and time again, you will see consistently and overwhelmingly positive reviews here on UU and elsewhere on the web about reliability of these instruments, the easy playability, as well as the excellent customer service from Magic Fluke Company.
I
do like the way they sound, but they sound DIFFERENT from most other ukes.
Not
everyone likes them for all the reasons that I, and a ton of other folks do.
If I could only keep 1 of the 10 ukes
(yes- UAS has been strong with this one) that I have acquired in the past 19 months, I would keep only my tenor Koa Fluke and ditch the rest.
