Bought one of these when I saw this thread and it arrived a couple of days ago from China.
Good news. It has a nice large display with good white backlight. The selector switch is pretty light but very usable and I like that I can easily turn it. Update speed looks good.
Not so good news. The backlight has a super short timer. And the continuity detector with stock probes is worse than horrible. You can short the probes and half the time nothing happens. The other half, it may latch in a second or two. I suspect the probe is responsible for a lot of this as when you short them in ohm settings, it reads all kinds of values until settling down to one ohm or so.
Anyway, I didn't buy it to have another multimeter added to my collection

. I wanted it for data logging remotely. Went to look for the Android app and could not find it in the google play market. Read the doc and it says it an .apk from their site! Go and download the thing, override Android security to install it and the system shows a boatload of permissions it is asking for including my phone id! And system access. No way as heck am I going to install some software from China that has not gone through audit of Google for malicious software.
I know it is some pain to go through Google and Apple certification but either do that, or cut down on the permissions it is requesting. I think it had 6 to 8 things it wanted to access. Little of that should be required to just talk to a bluetooth device.
I am going to find an old tablet to maybe use with it. Failing that, it is going to sit in the drawer for now
