Review: Long Overdue Tool Needed - I purchased this unit so I could test an AGM battery that constantly had issues. I learned alot about AGM batteries while researching battery chargers and battery tester. The Foxwell tester showed me exactly what was wrong with my battery. The unit is very easy to use and provides test results quickly. It is very sturdy. Clamps and cable heavy duty. It is definitely not built cheap. It has several testing options to choose from including testing your charging system. I like that it is powered by the battery you are working on as soon as you hook up the pos/neg terminals. Very happy with this tester. Decent price.
Review: Awesome Tool - This is yet another incredible product from Foxwell. This gadget performs multiple tests which are critical for diagnosing an electric issue with either your starter, alternator or battery. The settings are easy to use. Battery life is excellent as it's powered by the battery you're seeking to test. It's completely phantom powered. The accuracy of the unit when comparing it to more expensive testers is on par. This unit offers more utility features and tests that more expensive units fail to offer. The value for the money is incredible here. If you're a DIY mechanic, shade tree mechanic, weekend warrior or professional, don't miss out.
