Buyers beware ,this company is a fraud ,I purchased 500$ battery with 4 years warranty and appointment was set between 12-2 ,their tech comes before 10 am with different cheaper battery with 3 years warranty. I Call company and tell them I need battery I purchased with 4 years warranty they said they have right to substitute and they will not going to refund any $ back.They never email and let me know, so I refuse this cheaper battery because of $ I paid them ,they said they going to charge $99 for service fee which im going to dispute with my company because no service has been done.Beware , check your battery make sure they don't substitute with cheap stuff Terrible company However tech was 5+ star
