Majiloon Balloon Pump - The Professional (dual compressor- NiCad battery), making this the fastest electric balloon inflator in the World. This Majiloon unit is the ultimate in inflation. If you are an experienced balloon twister, you probably know about this pump. It is the best portable pump on the market, period. It sells new for $400. and has two compressors. Check out the Majiloon website for more details (.) I am selling it because I am doing very little balloon work anymore and use a floor pump on those occasions. This has been used very little. and has been sitting in my basement for the past year gathering dust - However - it is in excellent working condition and for all intents and purposes, functions as well as a new pump. Complete with battery and charger.
