I also agree, I have been using the Sirius charge for 5 years now and won't even consider purchasing a different brand. I had one problem with the indicator light at the 500 ma setting (I dropped the charger) and called Sirius. They had me send it in and they took care of MY problem and only charged me for the shipping. Even though you can buy less expensive chargers this type of customer service is worth every penny. And for anyone still using the slow chargers that come with the radios. I have probably doubled my flying days because I can decide at the last minute to go flying and plug in and charge on the way to the field. I haven't missed a flying day due to batteries in 5 years.
