But I'm not accusing him of being a shill or being compensated by those supplying the instruments....
Sorry if what I had said inferred or made you think that this was how I read your previous comment. I do not have the opinion that you called him a shill, but I was just putting it out there (and shooting it down) since it's not too far a leap...
I agree with most of what you had said above, with the exception about Kala in general.
My first uke that I 'bought' was a Kala KA-T that I got at local retail. It was fine out of the box, save for the action being a bit high, which I remedied by replacing the saddle with a shorter one. Intonation was +/- 5 cents which until I got a Flea, had no idea was bad. After the Flea with it's near-perfect intonation and getting my ear used to that, I could not play the KA-T as it was shipped. It was like nails on a chalkboard with the intonation being off.
I adjusted the nut slots each individually LOWER with a hacksaw blade, and ever since (this was over 2 yrs ago) the intonation's perfect up to the 10th fret, and +/- 1 cent beyond that. Now very close to my Flea and Fluke ukes.
Later on, I even installed a Mi-Si pickup in the KA-T. I've had no issues with it whatsoever. Now, nearly 3 yrs later it seems to have 'opened up'. This was my ONLY uke for about 6 months, and I played on that thing for at LEAST 2 hrs per day for those 6 months.
Also MANY other folks, who are not professional reviewers, but mere plebian UU brothers & sister here have bought plenty of $100+ Kala ukes and been VERY happy with them. most notable are the Cedar/Acacia/Padauk models 'KA-ATP-xx', which coincidentally are purchased from HMS, Mim, Uke Republic, and do a full inspection and setup before shipping of each instrument 'for free'. Folks have consistently said that these ukes both sound and play WAY above their pay-grade.
I played the tenor version of the KA-ATP last year, and if I had the cash I would have taken it home with me right at that moment.
SO, my point is that there may be a difference between lets say a random Kala bought off ebay or Amazon vs. one of the aforementioned vendors, vs. one that was cherry-picked and sent to someone famous for doing reviews, but I think it's unfair to write-off the entire brand when there is tons of evidence that in fact MOST of their ukes are not a waste of time and money.
Sorry you got burned on your Waterman. But to me, buying such a non-adjustable uke is truly the luck of the draw - no different than playing blackjack at a Casino. Some you win, some you lose. I dont enjoy such risks where total failure has a 50% or greater chance of kicking my ar$e. YMMV
