Bought the Maha C9000 charger from Paul. It is AMAZING. I am a professional photographer and carry about 40AA rechargeable batteries with me to each shoot. After a season of use, battery performance dropped significantly. I was just about to buy a new set of 40AA for about $150 and throw out the old ones, but then I thought I'd give this charger a try. WOW! This charger restored factory performance on ALL of them, it's like they are brand new! Buying this charger SAVED ME almost $100! And as a bonus, prevented 40 batteries from becoming environmentally bad waste. It's so awesome I bought two. And Paul is the epitome of the "Finest" customer service around. I expressed concern that Canada Post delivered my EXPRESS order significantly late. Paul contacted CP, got a refund for the shipping, and mailed me a cheque for the shipping charge. Paul is an absolute gem in this age of poor, infuriating customer service. I thank you for all your help!
