A feature-walkthrough from Kerry Wong.

DaneLaw:
Decided to purchase one of each at AliExpr's latest sale from two different stores, while the SG003A (blue) has arrived the more expensive SG-004A (yellow) hasn't - and not gonna arrive, as I sadly landed a dishonest Fnirsi-store/seller, that uses the old trick with an excuse about "quality-problems" after I paid.
And after some time, give an option to refund by PayPal.
Tried to explain it ain't an option, as the "price" people from Europe pay, also incl. VAT - so it needs to go through Aliexpress-system for those buyers to get their 25% VAT back..and it seems he wouldn't do that, as it will hurt his store, so instead put a fake tracking from Serbia of all places with an old timestamp, in an attempt to steal the money as the Aliexpress-system seems to accept that, even though Im in Denmark with my danish address, - and I as a buyer will be in limbo until the AliExpr. systems after a few weeks (or months) hopefully let me dispute it. - but that's "Aliexpress" in a nutshell, and something you need to tolerate if you wanna use that platform.

Usually, dishonest sellers will put some other persons tracking from your country, so it actually looks like it's heading your way when checking it, - I guess the tracking database these rancid sellers are using, was out of danish relevant tracking details.

it was the Aliexpress Store. "El Kitchen Store" (rancid fellow, stay clear of that store) even used a tracking that says delivered in Serbia before I made the purchase.-Aliexpress system is horrendously undermined if rotten sellers can use other peopples tracking that is "old" and already says delivered to another country (Serbia" before I made the purchase.
and the system won't let me dispute it... it says to wait 10 days... (I did) and now it says.. I shall need to wait and there needs to be at least 15 days of no activity on the tracking, and its hilarious as there hasnt been any movement on that tracking since 23 Sep where it was delivered to somebody in Serbia.https://parcelsapp.com/en/tracking/SY15030779787
Im in Denmark, how this Aliexpr.-system let him use an old dated tracking to Serbia is beyond me. (certainly not doing Fnirsi any benefits letting the most rancid stores on Aliexpress do this bs to customers)

The other Fnirsi SG-0003A (blue vers.) was purchased at Dylan Selection Store - and that was a pleasant experience, to a strong sale price, topnudge buying experience.

So far I'm quite impressed with how polished and well-built this product is from Fnirsi. (if they actually are making it, and it aint a rebrand from some third-party)
It feels well-built not least with the price in mind and it's a sexy little gadget. with tons of features.. there are a few spelling mistakes in the UI, and missing letters in certain places but it doesn't have that Frankenstein feel that I often have seen from Fnirsi, where it comes across as a mashup from other parts at the local market.
It's a nice little gadget for the price.

I purchased the SG-004A. Below are some photos of the teardown. It's pretty cool.

TheNewLab:
wow! looking at the SG-004A inside is like looking over New York City, while the inside of the SG-003a is more like..the Bahamas?  Just to add temp?  :-//

NoMoreMagicSmoke:
I purchased an SG-004A. Testing it out it appears to have a significant amount of (likely) thermal drift after first powering on. Once it stabilizes it appears to meet its specifications, but until it stabilizes, it is about an order of magnitude lower than is allowed by it's accuracy specification.
