Mantiz Saturn Pro Review - King of the Ring
Beware: if this glowing review sounds too good to be true, it is. One month after purchase, the fan started rattling so loud I could hear it through my headphones. Found out this is a common issue. Then after just two and half months, the Power Source Unit on my Saturn Pro completely died— as it has for many others, if you take a look around. Support has been super sketchy and unresponsive. After a week of emailing support they finally sent a prepaid DHL shipping label to return the PSU for a replacement. DHL shows it was received on April 16. I still don't have a replacement. It took another three weeks of emailing support for them to tell me "New PSU had been arrived on Friday. We'll arrange the delivery on Monday." That was on May 8. I've sent support 7 requests for a tracking number in the past 14 days, with no reply. I've seen many posts now saying that once they started posting on forums like this one, they finally got a response from Mantiz.
Actually, it's components are cheap— cables and PSU die consistently, plus their "customer service" is absolute shit:
Amazon's Top Critical Review: "The power supply has now died at 15 months."
I had the same thing, only my PSU took just 5 weeks to die. Still under warantee, but Mantiz support has been a nightmare trying to get them to replace it. The only time I seem to get a response is when I post complaints in public forums. Also, the fans clatter.
Update: on Saturday, John at Mantiz said replacement PSU would be shipped within two business days. I've followed up for a tracking number or confirmation of shipment 5 times since then. No reply. Honestly, how do these people stay in business?
If anyone has advice for how to put leverage on them, I'm all ears. I've posted negative reviews everywhere, and I'm about to take to Twitter and FB. Feels like I tossed $360 in the toilet 3 months ago.
@Doorkum, I think they're referring to the Saturn Pro 2 -
I just ordered one to NZ and it also had a dead PSU on arrival. This company needs to get the QA under control and stop pushing the costs of it onto their consumers.
Turns out either the USB-C ports themselves have died, or the controller in my laptop as I can no longer charge it using my old cable. Testing the enclosure out on a different laptop of the same model has worked great. My apologies to Mantiz for assuming the fault was with the PSU.
@pavel, In macOS with a supported graphics card, closing the MacBook Pro lid would switch to external display mode. In Windows/Boot Camp, you may need to set this behavior to not go to sleep so that the eGPU can continue working with Windows on external display.
Venus USB ports were not so good so really couldn’t be used for speakers, keyboards (anything needing lower latency). It was an early product though and one of the best at that time. Saturn tries to resolve the USB ports issue and generally has succeeded in this regard but has a few quality control issues, particularly in relation to the PSU.
Mantiz are trying to resolve issues but in some cases the support has not been very good, in terms of communication more than anything - but they are trying.
I think it is important to remember that no eGPU enclosure is perfect, this is a very niche product category. I would say the ‘dream’ of an eGPU is better than the reality, requiring tinkering in terms of software and accepting compromises on the hardware to get something stable.
Having owned Venus, Saturn Pro and also a Razer Core X Chroma. I would say the Razer is the ‘best’ in terms of out of the box stability and ‘plug and play’ but the PSU is bit noisy (doesn’t switch off fan), misses a sata drive internally. Software issues still exist but this is just as much the OS as anything else.
We can be demanding as customers sometimes. 🙂
I even opened another topic with some questions but without any success until now. Maybe you are so kind to take a look 🙂. Thanks
Does anybody have these problems:
- The system fan works constantly although GPU fans don't as the load is low.
- The system fan starts to be annoyingly noisy after about 10 minutes of work.
Just got around to picking one of these up. It has been better than my Razer Core X Chroma and the Sonnet Breakaway 750ex I tried in most every way. Except the noise. I spent a pretty penny and I don't see myself paying more to swap fans and PSU so I'll probably just return it and go back to my Razer Core X Chroma for now. It's a bummer in any case, because if this was as quiet as the others it would be pretty flawless.
