You get a lot for your money with the sensational Uma pulse concert ukulele.
Probably the first question you want answered will be "why fan frets?" The answer is in two parts. Firstly, the lower C and G strings benefit from a higher tension, which helps to make the tension across all 4 strings feel more uniform, and increases the presence and sustain of the low G string.
Secondly, the fan frets help to achieve slightly better intonation on these lower strings, which can have a tendency to veer sharp the higher up the fretboard one plays on a standard fretted ukulele.
So, not just a gimmick! You can certainly hear the precision in the intonation when you are playing in the first few positions. And, playing it in any position up the neck is remarkably comfy - you need not contort your hand at all, as you find that your finger shapes fall naturally into the right places without any need for major adjustment.
But seeing past the novelty of the fan frets, fundamentally this is a very good concert ukulele. This spruce topped model has a peppier, slightly crisper sound with a little more volume than the acacia model, whilst still being on the mellower side of the spectrum.
You are stuck with this in low G as well. Changing to a high G string would not work at all, as the intonation would be extremely skewy! So bear this in mind before purchasing.
