There are a lot of high quality chargers on the market nowadays,it really depends on your budget and level of racing you do.I've been using CE chargers for the past 5-6 years,and have never had any kind of battery issue.If you go to any national level race you will see more CE chargers than any other,that pretty much says it all.The much more chargers seem to be pretty nice but I still hear of some quality issue's,also their the new kid on the block and like anything it takes time to get all the bugs worked out for a new product.
