Very useful and handy

Nice tool to add to my toolbox. It is very helpful to save money and find out what the problem is and fix it yourself instead of taking your car to the shop.

Pros
  • One year trial
Cons
  • poorly thought out

Too expensive and not profitable!

I have to say that this battery tester does not work as described. It took me a long time to figure out how to use it. However, this is useless. I've never been able to figure out what the problem is, let alone fix the problem. And the price is too high. I definitely won't.

Pros
  • Price
Cons
  • Some difficulties

An impressive 2-in-1 tool, I highly recommend using it daily!

I'm really impressed with the quality and features it offers. I use it daily so it's holding up great. 1 is easier than carrying around two devices, it does everything I would definitely recommend!

Pros
  • Free for educational purposes
Cons
  • Upgradeable

If I could give 6 stars I would.

I've only had it a few weeks but have used it to diagnose two alternators, a lawn mower stator, several batteries and some fault lights on my car and my wife's truck. It is easy to use, clear, easy to read, fast and feature rich. I can't say enough good things about this code reader/battery tester.

Pros
  • Impressive
Cons
  • Modern

Useful and functional.

Nice little OBD2 scanner. Provides more information than necessary. You can test multiple systems and view information about your ECU. It is very useful to get codes from your car. It's easy to track the interphase. It even comes with a carrying case for easy storage. The battery test strap is a great addition. You don't have to guess why your check engine light is on.

Pros
  • Easy install
Cons
  • Disappear

Tester Champion

This is one of the best compact tester/combinations I have ever used. Easy to use, just follow the instructions and it works great. Sure, it's not designed to do what expensive testers will do, but I'd say for the average DIYer it does the job very well. When first used, it provided all the information needed and even pulled out the VIN and year of the car. When checking batteries, since I have both voltages, this is also diagnosed very accurately. Good offer in my opinion.

Pros
  • Easy to use
Cons
  • Only available in black

Amazing 2 in 1 tool to check battery health AND OBD2 diagnostic codes

I have many tools and combine them completely to solve the problem and carry less. I work on a lot of cars for fun so it's great to have a few tools that work great on cars old and new. I was working on a modern alternator rebuild on my old 61 Falcon and the battery test functions work great to check battery health before trying a new charging system. After 5 minutes I was able to hook it up to my wife's car to get an OBD2 code indicating a fuel vapor leak. Turns out she had left the gas cap…

Pros
  • Few competitors
Cons
  • Almost everything is ok

Super Convenient OBDII/Battery Tester Konnwei KW681

In my collection of car gadgets, I started Konnwei KW650 battery tester a year ago, then KW206 computer sensor and OBDII scanner. Then my son borrowed them both. Now I need a tester and can't wait for them to return it, especially now that I suspect I have a problem. These devices are in the same range, from $55 to $98. I wouldn't consider the highest prices for my expertise and I wouldn't have the lowest prices. My first choice was to look in the middle of the pack. This leaves several options

Pros
  • Handy Thing
Cons
  • Reliability
