the UNI-T  UT61D $43.19 from ebay is worthy ?

these ebay uni-t models are real or fakes?

I've a Sanwa CD770 and here are my comments on it..

I like this Japan built quality DMM but there are a few things missing ( the higher model have it at a much higher price ) :-
- Current measurement, only 400mA, no 10A
- no backlight

Overall, I am satisfied with this model, pretty fast readings and good accuracy ...

I haven't seen fake Uni-T meters. Fraudsters, when going through the trouble to fake a meter, like to target the high-end brands, because the margins for the fraudsters are higher. Uni-T is low-end stuff. It is not the bottom of the barrel, but it is nothing to write home about. They aren't high-end meters in stealth mode. You get your $43.19 worth, but not more.
I delete PMs unread. If you have something to say, say it in public.

for me, this is to be taken seriously, i will trash any dmm model from my recommendation list if it cannot do 10A (unless it has very special feature that other dmm cannot do). i recommend Unit-T... reason? i own uni-t71a, how good it is? i'm not sure, but i believe it serves my purpose, i just will not expect it to be higher or the same as more expensive unit. i got what i pay. and Dave reviewed Uni-T without any serious comment/issue.

if something can select, how cant it be intelligent? if something is intelligent, how cant it exist?

yea really unless you know you will confine yourself to low power stuff you need a meter capable of 10A as a first meter, after that look at meters that are more niche but good at what they do

you need a meter capable of 10A as a first meter

The second would be 25A ?   And the third 70A ?  :D

The first one could be what ever you can find, experiments with small batteries does not need
that power in Ampere .  

UNI-T will be fine as option.

Well I'm sure one of the first things a hobbiest may do is use a car battery as a power source and want to measure charge and discharge of it. I say the first meter should be general purpose with a 10A range, after that you could get a more niche meter with only 400mA but hopefully that would be a better quality meter or have other nice functions

Got my mind made up, it's Amprobe AM220.
Thanks for the comments
