I have just become aware of (and ordered) the NX31. In the image here I have de-faked<\/strong> the dials back with a 86% factor!<\/p>\n

\"\"<\/a><\/p>\n

I had edited this posts a few times but it is not worthy a full review, not recommended!<\/strong><\/p>\n

<\/p>\n

From the listing it is supposed to me 8mm thick, \u00f841.1mm and 47.6mm long, with a \u00f81.32″=33.5mm
\nIn reality it is 10.5mm thick, and 8.5mm towards the edge. The screen is curved, and protrusion cover a very large part of the back.
\nAs usual hard to find the manufacturer, but I bought it from some seller on Aliexpress here<\/a>.
\nIt is also sold as “NX21” – and likely many other names, can be recognised by the print on the back “220-JP7653<\/strong>” though that number is ALSO used for a smartring<\/em>(HC-02-9), so something fishy here…<\/p>\n

\"\"<\/a><\/p>\n

\"\"<\/a>
\n…I guess neither really got a certification<\/p>\n

Here some key specs from the listing (click to enlarge)
\n\"\"<\/a>
\n(If the rendering is correct, the full thickness including the large \u00f823 area flat protrusion is 9.2mm<\/del> is 10.5mm<\/em>, and the band very narrow at 16mm)
\nAnd they certainly should be praised for being honest about the length – That is rare!!! – though strictly speaking it is 47.75mm, but that 0.3% might be specimen variation.<\/span>
\nThough it is quite long for a watch that by the \u00f841.1mm indicates that it is aimed at minor wrists.
\nIt is 1.25mm longer than the 0.1mm less wide H06<\/a>.<\/p>\n

Searching a bit on Alibaba led med to this<\/a> link from a possible distributor “Sibotesi<\/a>” Note that the link says “Sportscam” and the logo “IXIU”….??
\nIn the listing they mention that the app is “FitCloudPro”, and in my experience is that not a good sign, so I fear it is a crappy watch…<\/p>\n

That sellers page again led me to the existence of the G34<\/a>, that I will try to dig into….<\/p>\n

 <\/p>\n

The G34 uses a different app and chipset, so most likely it is just a distributor I have found, that distributes both the G34 and the NX31 watches.<\/p>\n

 <\/p>\n

Conclusion<\/h3>\n

Generally the NX31 just feels like crap, and also gladly claims reading HR, BP and SpO2 of a wooden table!!!<\/p>\n

It only got 8(!) workout modes, that is the least I think I’ve ever seen.
\nBut to say just something positive, apart from the cable it came with both a screen protector and a manual. I did not try to apply the protector, but unless it is rather elastic it will not work on a curved screen…<\/p>\n

Packed down, and most likely will never again see the light of day… Wasted money…<\/p>\n","protected":false},"excerpt":{"rendered":"
