Over priced for what it does.
Hi John, we're sorry you felt this way about the product. May I ask what features you were looking for?
This is an excellent Multimeter.
Super good stuff
Received today at 2:00 pm, by 2:05 pm I am almost ready to send back. The red Alligator clip broke. Have not even hooked up to a car yet. Hopefully PP people read these reviews and step up, and issue me a new one We will see what happens.Dave.
Over priced for a dmm with 6000 counts and no min/max features, poor battery life. No manual override on that smart auto detection feature. I have to use a cheap hf ames dmm for min/max, smh! 🙄 I'm to late for returning. I'm a tech with 20 plus year of experience.
