In March 2021 i decided its time to get an Oscilloscope. So i start looking around and found the Hantek DSO 2D10 with integrated functiongenerator.
After some looking i found the official Hantec Store on AliExpress wich offered 7 day delivery from Czechs Republic and i thought great no Customs cause im from German and EU internal there normaly is no customs, so i ordered it on March 18th. for around 200 Euro (~ 245US$) ang got it delivered just 3 or 4 days later.
Here the first dissapointment came up. The Scope came with only 1 Probe. so i got another probe from a friend who had one spare.
I have played around a bit with the function generator and the scope to get used to the trigger and other functions. Last time i used a scope was 20+ years ago, good old Hameg and Simens 20Mhz analog scopes.
So far everything worked fine even the display and colors wherent that greate. They used yellow and green for the 2 channels wich where quite pale and the difference was hard to recognise.
But so far i was quite satisfied with the Hantek DSO2D10 so far. But then, the nightmare begun.
After i got used to most of the functions i decided its time fore some real messurments and protokol decoding (i2c) the reason i mainly bought the scope for.
For my project i wanted to decode some traffice on the i2c bus between an ESP32 and an ADS1115 ADC.
The protocol decoding was well mehh not so good as it was described, but that was my least problem with ths scope.
To catch some data i set the timebase quite low and manually set the memory depth to 8m and the scope froze.
It didnt react to any inputs and i had to resart it. Well i thought it mit be just coincidence or i did something wrong.
After rebooting the scope i did some more messurments but as soon as i used the full 8M memory depth the scope froze.
This time even a reboot didnt got the scope out of its frozen state and it didnt react to any input. even after multiple reboots so i contacted the Hantec store on AliExpress.
They didnt respond for a few days so i contacted the Hantek support directly.
The technican send me an email with instructions on how to set the scope to maintenance mode and how to install a complete new operating system (Notice Operating System not Firmware!)
After that the scope booted up normaly again, but the problem persisted.
As soon as you used a memory depth above 4M the scope froze during messurments.
Meanwhile the Shop also responded and keept asking for more time to find a solution to the problem.
Im usualy quite patient so i gave them a chance but nothing happend, they keep asking for more and more time.
So i told them i claim waranty for a not functioning device. Again they didnt respond tor a couple of days.
Since the Scope works on a Linux operating system the problem indicates a defective memory.
So i decided to make a video of the frozen scope and opend a dispute on AliExpress.
Again the official Hantec store played on time and only react just befor the deadline.
AliExpress ridiculously suggested to keep the frozen, not working scope and acceppt a refund of 20 Euro (~24US$) for a 200 Euro Scope.
The dispute took nearly 3 weeks and i had to return the scope. The Hantek Store insisted i have to return the Scope to china, not to Czechs Republic where it was delivered from. The Shop also Insisted i have to send it via express Airmail.
That was another 50 Euro (~60US$) of shipping costs i had to pay for.
So by now i payed about 250 Euro (~300US$) for a not working scope i also didnt have anymore
By now the scope is at the chineese custom for over 2 weeks but Hantec dont care about and didnt try to clear customs what is in their responsibility.
Instead they claim they didnt receive the scope and delaying the refund even more.
So by now im waiting for over 2 month for the refund of my Money. I didnt even know if Hantec will refund the shipping costs even they promised and i fear they wont.
250 Euro and no scope, just a tracking number which says item not cleard for customs by receiver.
Meanwhile i calld a lawyer asking what i can do now. He recommended to me to get a court order against Hantek czechs Republic and to have the bailiff enforced it.
However, that means that I have to advance more money, which I would then also have to sue
So my oppinion and experience, NEVER again anything from Hantek
Meanwhile i own a Rigol DS1102Z-E that was only slightly more expensive then the Hantek and it works like a charm, have way more and better otions for messurments and protocol decoding and came with all options ( triggers, decoding, memory and recording) licensed, it even have 3x the memory of the Hantec (24M) and costs me about 260Euro (~315US$) on Amazon
