Very well pleased!

I was really suprised to find a sturdy well built and easy to use device at this price. After shopping around for the more expensive options, and reading their not so favorable reviews, I was about to give up, until this Innova 3320b popped up in my feed. After reading reviews and watching videos, I decided to take a chance and I am glad I did. This device is just right for me. I did see a negative video about this wonderful device, yet I could perceive there was probably a paid monetary gain for producing a negative and misleading report for the competition can not compare at this price .

Ideal shopping experience

I give an "excellent" rating to all the rating criteria because everything from product browsing, descriptions & specs, purchasing, to shipping speed & cost was positive. No negatives or caveats. BTW, the Equus 3320 multimeter is the only multimeter on the market that is flexible enough, simple enough, AND inexpensive enough to use solely as an all purpose, all variety battery tester - from 1.5V button batteries to 12 and 24V vehicle batteries. All other battery testers are either much more limiting and/or difficult to use and read, or much more expensive. I got it for my in-laws to use so it has to be easy to use. And, of course, it is a multimeter and can thus be used for more than just battery testing. Hopefully the product longevity will be good also. So far I consider the product to be very good.

accurate and sturdy

A little more expensive than some meters, but worth it. The plastic case is very sturdy and will take some rough handling. The clips on the sides for the probes are very useful. I am hanging my meter on the wall near my workplace. There are straps on the back to help you hold it when you are away from your bench, and a folding stand.
