ST5S Professional LCR Meter/ESR Meter with Spare Test Leads and Pocket Case

I'm using it primarily while working on prototypes of industrial automation control devices - the instrument works exactly as described, I had no any glitches or malfunctions yet. Great aid for repair, building or tweaking up boards with small SMD components (those seemingly gold plated tips it comes with are easily landing on 0402 footprint components and are of good quality overall - the "shorting" resistance is less then 40 mOhm) - saves alot of time in comparison to frustrating process to do that holding probes of conventional multimeter as chopsticks. Fast and accurate (compared with readouts of benchtop Fluke multimeter) readings, crisp graphic OLED display, plenty of measurement modes and presets (including, for the instance, caps ESR, diode voltage drop (useful for transistors as well) measurement, etc. The thing like these tweezers becomes exceptionally useful for finding right replacement components to scavenge from scrapped boards for resuscitation of device being repaired. The interface is convenient and reasonably intuitive for such small instrument - the brief look at supplied "menu tree" card and you got it (e.g., the "joystick control" has direct shortcuts to common measuring modes and parameters setup.

I am very satisfied with the purchase, very useful and very precise

Update: Advance Devices contacted me and helped me to restore the tweezer I had, there is an issue with the processor going into sleep mode on the version I had (I suggested they add more details to the manual or creating a troubleshooting guide.) They also shipped me a new version of the tweezers that do not have this problem and have some other improvements. I am back up and running, and using the new tweezers. Thanks to Advance Devices for the great service, have no reservations, if something goes wrong, Advance Devices will take care of you. Original review: I design high performance analog circuitry for a living and have worked designing electronics for 20 years now. I work on the highest performance circuitry in the world. I've recommended these tweezers to friends in the industry, and right now I am wondering if I steered others in the wrong direction. I loved these tweezers for the first 6 months, really makse testing surface mount components fast and easy. But when I went to use the tweezers recently, they would not turn on. I checked the cables and charger, tried a few different options, other device that uses the same charging port charge just fine. I get nothing on the display, just completely dead. More than a little disappointing given I have only had them 6 months. The company has no information on service, warranty or otherwise. I sent an e-mail, and got no response. Maybe they are small and on vacation? I am going to try and call, but thus far it seems the customer service is non-existent from the manufacturer, and appears that it is going to be a pain for me. Unless/until the company responds, I will be giving this product 1 star and I do not recommend that you spend close to $300 on this item when service is so questionable. Hopefully the company won't continue to be MIA and will stand behind the product they are selling. I will update my review with new information.

Accurate and ergonomic LCR meter. Great aid to repairs. I am going to get it upgraded to a Bluetooth version

A high quality product but expensive .The ESR measurement works fine and it is very important when you are testing electrolityc capacitors in high frequency .

While pricey, the investment has already paid off in trouble shooting a complex board that has numerous 0402 components. I'm surprised by the accuracy, although I wish it would go to 100 kHz to better isolate the component under test from the rest of the network. In a matter of minutes I found the bad component. When I removed it from the board I found that excess flux had prevented it from bonding to the pad, leaving the trace partially open. While other instruments at a lower price will work for larger components, this seems like a very good tool for the really small stuff. I have also found it good for sorting components that are in cut tape, but not clearly marked. I have a pile of resistor values where the printing on the tapes was illegible. I can use the Smart Tweezers to poke through the tap and contact the component to take a measurement without removing it from the carrier.

I have really enjoyed using this device. So simple and so many features. Even bluetooth to a computer for display and logging. Best one that I have ever tried. I purchased for my hobby of testing and fixing audio equipment. It's best for SMT parts but cal also work on discrete components as long as the terminals are not too far apart. One of my favorite electronics tools.
