The OP’s experience highlights a particular value in visiting and buying from a bricks and mortar store: the same (model) instrument can be and too often is different and some instruments should never have got past the factory’s QA department but did. Of course beware of glib salesmen and pressure to buy; go to a store to thoroughly test and select and if that’s not happening then walk away.
I rarely buy instruments in a store visit, to an extent that’s a reflection of my preferences and then there’s the lack of a suitable store to visit within easy travel time. Instead I take pot luck on-line with second hand instruments and have ended up sorting many out with pleasing results

, nothing near as expensive as an S1 though. Mail ordering a new Uke is something that I’ve also done but, and I might have been unlucky, the shop reputations and assurances of high quality have not proven reliable … someone must end up buying the Ukes that the in-store customers reject. My biggest lack of luck with mail order was with my most expensive new instrument and in hindsight I should have made a fuss and sent it back.
Bruko’s, I’ve had a few through my hands but, after a good set-up and test, always sold them on again and just about covered my out of pocket costs. I liked the very high manufacturing quality of my Brukos (No 6’s), but mine were all very percussive and (to my ear) dominated by the A string; some might really like that but it wasn’t what I was looking for, YMMV. WW, a well known member here on UU, plays a No 6 but he hand picked his and has played it for years and years … the same instrument can be different and there’s a particular value in visiting and buying from a bricks and mortar store.
Good luck with the S1; there might be better instruments out there and some might be better value but I feel sure that an S1 is amongst the better Sopranos available … and so long as one can afford it the price is acceptable enough.
