Review on KONNWEI KW510 12V 5-Amp Smart Charger with Car Battery Tester - 3 in 1 Automotive Pulse Repair Maintainer, Trickle Charger Battery Desulfator with Temperature Compensation by Affan Yeo

I bought a Konnwei 5 amp charger/analyzer because of the features, price and good reviews. The item I received did not work when it arrived - the analyzer worked but the charger did not work. I contacted the support team who responded within 24 hours and asked me to shoot several videos of the malfunction. After I submitted the video they sent me a replacement charger - I didn't have to ask, they were active. The replacement charger/analyzer is working properly. I'm glad the seller stands behind the product and is interested in analyzing the issue, presumably to improve quality control. The characteristics of the product are as described and it meets my needs well. Satisfied customer. Because of this good support, I order another of their products (OBD analyzer).
