I was not going to pull it to bits as I have been posting too much as of late , nearly spamming the website imo , but I also notice at the same time there does not seem to be a picture of the pcb anywhere so far looking about .
A picture of the PCB would be informative, as little is know about this company. Seems that everywhere you look in China, a new DMM manufacturing firm appears out of the woodwork. While spending time in China, I came to realize that there is a lot of cooperation between manufacturers. If one firm gets a large order it can't fulfill straightaway, the work gets farmed out somewhere else.
The meter should be safe enough if you stick to a CAT II 250V rating environment, especially with the A/mA jack blocking system.
Don't expect very accurate measurements though. It has the worst specs I have ever seen on a true RMS 6000 count meter.
