The first configuration screen could be clearer for beginners. The miner does the basic job, but the setup was less intuitive than I hoped.
Nicolas Thomas –
Le concept est int¨¦ressant lorsque l¡¯espace disponible est limit¨¦. Le refroidissement est rest¨¦ constant dans ma pi¨¨ce. Il fait partie d¡¯une petite installation d¡¯apprentissage. Pour un appareil de loisir, l¡¯assemblage para?t propre. Apr¨¨s plusieurs soir¨¦es, je n¡¯ai pas constat¨¦ de red¨¦marrages inattendus. Les performances correspondent globalement ¨¤ ce que j¡¯attendais. Le format compact a beaucoup compt¨¦ dans mon choix.

Ocupa muy poco espacio en mi escritorio. Lo prob¨¦ durante un fin de semana. Una caracter¨ªstica ¨²til de este modelo es 8,1 TH/s, 138W y refrigeraci¨®n con tres ventiladores. Tras varias noches de uso no he visto reinicios inesperados. El consumo es f¨¢cil de controlar.
Tobias Schneider –
F¨¹r kleine Tests w¨¹rde ich es wieder verwenden. Der Stromverbrauch l?sst sich gut im Blick behalten. In einem sehr ruhigen Raum h?rt man den L¨¹fter, f¨¹r mich ist das aber noch in Ordnung. Der kompakte Formfaktor war f¨¹r mich ein wichtiger Kaufgrund.

Mine sits beside my router. The combination of 8.1 TH/s, 138W and three-fan cooling is what made me try this model. The cooling solution seems appropriate for the amount of work the unit is doing. I would like a few more controls in the interface. I appreciate that the specifications are modest enough for a normal room. It has been a fun way to experiment with solo mining.
¨¦lodie Bernard –
Je l¡¯utilise surtout pour apprendre et faire des essais. La consommation reste facile ¨¤ surveiller. La finition donne une impression s¨¦rieuse. Je vais le garder dans mon installation de test. Je m¡¯attendais ¨¤ une premi¨¨re installation plus compliqu¨¦e. Les performances correspondent globalement ¨¤ ce que j¡¯attendais. Je le fais surtout fonctionner l¡¯apr¨¨s-midi.

La messa in funzione ¨¨ stata pi¨´ rapida del previsto.

I have used it mostly for testing and learning rather than chasing returns. It is convenient for someone who wants to learn without building a large rig. It reconnects cleanly after I restart my network. This is part of a small learning setup. Cooling has stayed consistent in my room. The result has been positive for my use case.

Der kompakte Formfaktor war f¨¹r mich ein wichtiger Kaufgrund. Ich nutze es haupts?chlich zum Testen und Lernen. F¨¹r Experimente mit Solo-Mining macht das Ger?t Spa?. Nach dem ersten Tag ist es vom Regal auf den Schreibtisch gewandert. Im Vergleich zu gro?en Minern l?sst es sich zuhause deutlich leichter unterbringen.
Chris Miller –
After several evenings of use, I have not seen unexpected resets.
Julia Schmidt –
Aufmerksam geworden bin ich vor allem wegen 8,1 TH/s, 138W und K¨¹hlung mit drei L¨¹ftern.
Julia Wagner –
Im Vergleich zu gro?en Minern l?sst es sich zuhause deutlich leichter unterbringen. Nach mehreren Abenden hatte ich keine unerwarteten Neustarts. Die K¨¹hlung arbeitet in meinem Raum konstant. Ich lasse es meistens am Nachmittag laufen. Im Alltag ist es praktischer geworden, als ich anfangs dachte.

Daniel Davis –
For a home environment, the size is much easier to live with than full-size mining gear. I like that it feels more like a hobby device than a large industrial miner. I moved it from a shelf to my desk after the first day. I appreciate that the specifications are modest enough for a normal room. What caught my attention on the spec sheet was 8.1 TH/s, 138W and three-fan cooling.

It has been a fun way to experiment with solo mining. I compared it with another compact miner I already own. I moved it between two rooms and did not have to redo much configuration. The specification that stood out to me was 8.1 TH/s, 138W and three-fan cooling. It settled into my desk setup without taking much room. The cooling solution seems appropriate for the amount of work the unit is doing. It reconnects cleanly after I restart my network. It is convenient for someone who wants to learn without building a large rig. I moved it between two rooms and did not have to redo much configuration. The fan is noticeable in a quiet room, though it is not a deal breaker for me.

Auf dem Datenblatt ist besonders 8,1 TH/s, 138W und K¨¹hlung mit drei L¨¹ftern interessant. Ich nutze es haupts?chlich zum Testen und Lernen. Nach einem Neustart meines Netzwerks war das Ger?t schnell wieder erreichbar. F¨¹r Experimente mit Solo-Mining macht das Ger?t Spa?. Ich lasse es meistens am Nachmittag laufen. Auf dem Schreibtisch nimmt das Ger?t erstaunlich wenig Platz ein.
Nina Becker 2 –
Ich konnte das Ger?t starten, hatte in meinem Setup aber wiederholt Stabilit?tsprobleme. Ich lasse es meistens am Nachmittag laufen. Vor einem stabilen Betrieb war deutlich mehr Fehlersuche n?tig als erwartet.

Le informazioni di stato sono abbastanza facili da seguire. Mi aspettavo una configurazione iniziale pi¨´ complicata. La costruzione d¨¤ una buona impressione. Dopo il primo giorno l¡¯ho spostato dallo scaffale alla scrivania. Il consumo ¨¨ semplice da tenere sotto controllo. Un punto interessante di questo modello ¨¨ 8,1 TH/s, 138W e raffreddamento a tre ventole.

Konstrukcja sprawia solidne wra?enie. W specyfikacji wyr¨®?nia si? 8,1 TH/s, 138W i ch?odzenie trzema wentylatorami. Og¨®lnie pasuje do hobbystycznego zastosowania, kt¨®rego szuka?em. Na biurku zajmuje naprawd? ma?o miejsca. W domu jest znacznie ?atwiejszy do ustawienia ni? du?y miner. Informacje o stanie s? wystarczaj?co czytelne. M¨®j stoi obok routera. To ciekawy spos¨®b na eksperymenty z solo miningiem. Po restarcie sieci urz?dzenie szybko wr¨®ci?o online. Ustawienia sieci musia?em zapisa? ponownie. Konstrukcja sprawia solidne wra?enie.

Just finished setting up my Stell Apex NerdQX 8.1 terahash miner, and I gotta say, the build quality is genuinely solid—feels like a well-made piece of hardware. The fans do feel a little thinner than I’d expect, which leads to slightly higher temps and a bit more noise than I’d like, but overall the quality holds up well. It’s been running reliably, and I’m happy enough with the performance to give it four stars. Solid choice if you’re in the market for one.
