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

100% recommended.
Fantastic tool.

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.

Seems quite accurate, more than enough for my needs. Comes with spare tips, a storage case. There's a magnet in the back for sticking it up near your workspace. The screen is pretty large and bright, and it is rechargeable. I like that you can change the test frequency a bit. There not a lot not to like, these are awesome for the money.
