Good kit. The problem is that the batteries in the multimeter are one of those cheap Chinese brands that have LEAD in them. The battery must not be disposed of in American garbage. Instead of spending 20 yuan more on an alkaline battery than they can safely throw away, they decide to poison the environment. I don't give this money any value because once you buy this kit you will have to spend half an hour taking the TOXIC WASTE BATTERY to a safe place for disposal. It's absurd that they allow it to be sold in the US. China legalizes toxic batteries that cause learning disabilities in children. Please skip this product until they pass a law banning these toxic wastes or until the manufacturer includes non-toxic batteries.
