Great Smd Testing Tweezers
These are awesome nice and small with inductors included in the test I find them to be more accurate than my uni t one and the case is a great addition to keep them dust free and safe.The unit has a 3 set frequency test condition which if it is slightly out you can set a different frequency and I have tried this and it does work quite well,There is a spare set of tips and they are right angled,I am happy to give these 5 stars as I think they are awesome.

The best present ever!
My wife bought me this for Christmas and it has changed my life! Well, my workflow anyway. Great tool for troubleshooting and multi-frequency esr testing to boot, all one handed. Simply awesome

Inaccurate measurements.
I bought this mainly for measuring capacitors during repairs. The first 2 I measured were approximately 20% low. I tried the same capacitors with my multimeter and they were approximately 5% out. I then tried several new capacitors and all measured approximately 20% low. The same capacitors tested on a different multimeter measured around 5% low. Unfortunately this will be going back due to the inaccurate measurements.

Nice little tool,

Where have this been all my life! This small device is the greatest tool in my lab! It automatically detects the passive device and tells you the value. It’s so easy to use, features resistoance, capacitance, inductance readings with high accuracy. It’s very ergonomic and very thoughtfully designed. Better than your traditional multimeter and is a MUST HAVE!

Works great. Perfect for identifying tiny SMD parts. Easy to read display. User documentation (English version) is adequate, but a little hard to follow.

Impressive little item I must admit.

When I first saw this, I thought this was a gimmick, but a friend convinced me to try it. I was pleasantly surprised by how well it works. The component readings are accurate. The screen size is large and bright enough to be functional. The user interface could use some improvement, and the tips could come together better, but I will overlook those for how well it works overall!
