Nice Tester
Seems well built. The leads are a bit longer and thicker than one I paid the same Amount for. The clamps work good. The tests appear accurate. I would Recommend. ( I am not an expert)

So far so good but ...
Hi, I only have this a couple of days so far so good as far as the battery test goes, seems to be close enough to what my multimeter voltage readings say. I've been charging my battery and testing as I go with TOPDON BT50 and my meter ,so far voltage readings are close enough with both. I haven't been able to do the crank /charging tests as my battery isn't hooked up to my car, because I'm still charging up my battery with a charger so I'm only able to do the battery test, these other tests will come later on and I'll update when battery is back in car. As far as ease of use, this gadget is so easy to use you could do without the small manual. As of now, I can say I recommend it, very handy and seems to work great ,only gave 4 stars because I wasn't ready to run the other tests due to battery not being in car. I will update.

Good tester with a few flaws.
Pleased with the tester except for the connecter grips. They do not appear to grip very well and the black and red cords are not long enough, in my opinion. The tester works as expected and gives the results of the battery. Due to how well it preforms, I had to replace two batteries.

Works well, responsive customer service
Works well. It has been a big help dealing with typically challenging battery situations with my boat and RV. And helped diagnose a car battery problem. (Update ) Customer service is excellent, very responsive. New model has greatly improved clips.
