Nice,
i love my hameg. This one is round about 35 years old. The function generatr abouve just 1/2 year.
I had several UNI-T's, i think they're ok, but i didn't try to get support or repair something.
Don't be angry with me, but 12 years for a digital device from China is a decent amount of time.
A little true story on the side:
A well-known company here in Germany once developed a small digital radio that you could build yourself. It was such a kit with instructions with the background to convey some electronics and at the same time to have a nice project. The edition was only a few thousand pieces. This radio was manufactured and assembled in China. Also the software of the little chip. The part became a box office hit. Only 1 year later they wanted to relaunch the radio again. However, they only wanted to make a few small changes to the software. Like I said, a year later. But no chance. The software had to be developed from scratch, because none of the Chinese partners could remember that software. No version control system, no backup, even the employees couldn't help. Of course, the software could have been read out of the chip and disassembled. But the effort was equal to a new development.
