Title: My Pangolin Nightmare now halved but persists...
Post by: Philopolymath on December 10, 2019, 12:32:00 AM
I'm done with Pangolin and Microbit...Absolute Junk and ridiculous return costs and lousy follow up service..My Units have used bodies that still have glue from removed stickers on them and other obvious signs of use and wear.
My nightmare continues and now just more money out the window for ZERO BTC mining done.
Oh and the ONLY way to get tech help is through Telegram and give them remote access to your comp via TEAMVIEW

2 MAJOR security risks not to mention you must download and install and learn how to use both..And co-ordinate a time to be online with someone 12 times zones away during THEIR working hours.

Even then they will only tell you what you already know...THE UNIT IS DEAD and you must return the WHOLE device.

Lousy software/firmware...
They advertise low power setting...there is even an option in the software...BUT it's NOT enabled/supported...WTF that was the ONLY REASON I BOUGHT FUCKERS was for the high efficiency
The units that do work have no fan control  just always 100% regardless of chip temps...and they have lousy cooling they get HOT fast and are VERY LOUD.
They arrived a week late

Any chance for profit has been wiped out completely....I will never even come close to earning enough to pay for the defective/returned unit


They are worse than Bitmain....


UPDATE JAN 23rd
So I have got back ONE unit and it is working to spec..And they did pay for the shipping cost to return the unit to them. (reimbursed me actually)
However the second unit was diagnosed as having a connector board problem.
They did not offer to send one immediately...In fact the wanted me to BUY one !!!...for a unit that arrived DOA !!
No they included a new board with the repaired unit...Well it came and I very CAREFULLY replaced it and confirmed the original did have damaged/missing pins.
But there is STILL one dead hash board EXACTLY as before....
They have not responded to emails and I am still waiting to hear from Mr Yan on Telegram IF and or HOW they plan to address the problem..

They were removing stickers and leaving glue like that since M3 models. Some people thought it was because they were originally branded as the scam Kodak KashMiner. The real issue may have been from pending litigation with Bitmain over their PSU patent and claims their former engineer, who founded MicroBT, stole designs. That patent was supposedly revoked during litigation, but there was recent news that he was being held by police for new intellectual property infringement claims made by Bitmain involving tens of millions of yuan. They are probably removing the stickers again to avoid units being seized.

I mean if they recycled chassis that's awesome. It's a metal tube might as well recycle it no?

Shitty, sorry to hear about that. I've dodged dead units so far. I had a limpy t9+ so it was an easy decision to not send back the entire machine for a simple repair and hope it came back working. That's always been the biggest BS policy around that you pay the return shipping for this gear when it arrives dead.

I got lucky with Pangolin. They tried, but I hated having to be on TG and using Teamviewer to essentially watch them load a couple firmware versions hoping to fix my issue. In the end I was still left with an erratic unit that couldn't handle LP mode very well. So a small loss when compared with shipping costs. My problem was a little different as the unit would run just not as well as it should have, so I made a case for at home repair to try and swap out possible issues like a PSU or a bridge.  

Personally I would try and get them to cover half of the return shipping costs or something. Play the you were late card, and the fact that you purchased other units from them. It never hurts to ask in these situations.

The glue/sticker issue they have said on telegram was to facilitate smooth shipping and export/import. I guess that's a reason.

I got

1 m3
8 m10
1 m21s
1 m20

1 m10 was a piece of garbage basically an 800 dollar loss.

all other gear was okay.

although right now 1 m20s is down and i dont know why. i will look at it on friday the 20th

what really hurt whatsminer was the really slow shipping for the august purchases.

And now my second M20 died after less than 5 hours. Glad I did not sent it off to host before testing.
So almost 5 months since paid for in full..... and I have two useless miners.
The first unit (Returned) arrived in Shenzhen 2 days ago but has not been picked-up yet.

to up date my dead pangolin m20s.

it fried the psu.

not surprised as they really pushed the shit out of it.

it drew 3400 watts 24/7/365 out of a rated 3500.

it did run from may to dec. it was a beta model.

i found a company in north carolina

hmtech

they sold me a new psu for 275 shipped in two days.

the psu frompangolin would have been 150 + 58 = 208 plus some tax maybe 225.

so,it did cost more but i got it four or five days faster then pangolin so it earns 40-50 bucks in that time it is breakeven.

since my gear was out of warranty and beta.  i had a p20 psu not a p21

i had may firmware for a h6 controller not a h3.

so i flashed with pangolin liinked firmware. it did not work spent time on microbt website found h3  and h6 firmware. flashed with h6it took and my m20s is running. lost 17 days of mining and paid 275 for psu.


could be worse. i could have your issues which would be more costly.

Over 6 months now and I still have one dead M-20 unit....they have not replied to emails for over 1 month. while on telegram no reply since I notified them the diagnosis and instructed repairs of board replacement did not solve the problem the unit is still defective. 2k U.S. rip off for ZERO return.

That sucks. Bitmain is just as bad for warranty IMO although I've never dealt with them for DOA. My Z11 had the middle hash board fry in less than two weeks. I couldn't even pay them for a replacement board and have been running it with two boards since. The only company I've ever had good luck with sending me replacement parts for free under warranty was Canaan.
