Must have for amp repairs.
Saw Uncle Doug using this on YouTube and thought I should get this as I had an old Fender amp I was restoring. This is the tool to have for checking old electrolytic capacitors.

Disappointed, overrated
This is the worst piece of test equipment I ever purchased! Don't waste your money! My opinion it's junk!

Excellent product for testing caps.
Already used to test and ensure one of my caps that got too hot wasn't ruined, and it tested great.

If you want an ESR meter this is a good one
I have been rebuilding old Marantz amps and this is a great tool in that process.

I really like this meter. Saved tons of time !!!
Works well. I ordered tweezers for making it easier to test on board components. Even without the tweezers, this esr meter is easy to use with an easy to read chart on the front.

Very useful to identify bad capacitors that otherwise would not be detected. If you repair or work with vintage electronics you need this.

J’ai hésité un bon moment avant de commander, car je trouvais dispendieux comparé à d’autres testeur, mais je ne regrette pas. Il fonctionne parfaitement, et c’est un des rare à pouvoir mesurer l’ESR avec une présence de tension, jusqu’à une certaine limit (pratique pour mesurer la résistance interne de batteries). Je m’en sert principalement pour tester des condensateurs, couplé à un multimètre pour tester aussi la capacité, c’est un outil parfait.

I was expecting a pair of prod with it.

Naively thought I wouldn't have to pay duty on this product. That is the only down side in buying product from USA to Canada. Otherwise this is an excellent piece of test equipment.
