Great device to check car batteries

Great quality device and works as described. Well packed and comes with a case. Delivery from Hongkong to UK took 2 weeks, hence 4 star. FNIRSI product look quality products will buy their other devices.

Quality products

I appreciate doing business with this company. However, check the printing of advertising. I like the manner in which my item is wrapped & mailed to ensure that the box can not be so easily opened during the delivery process. Also delivery time is fast. Keep up the good work.

Battery tester

Tested more than 60 batteries 12V 7-9AH without any issue and very fast response. I would like to see a pass /fail indication based on the battery setup. I’d like to have more detailed battery setup so the results could be more accurate
