Owning two batteries for my portable Oxygen Generator was becoming a hassle. The generator would only accommodate one battery charging at any given time. I visited many Web Sites searching for an external charger and after viewing the prices I became disappointed of how much these sites were charging. Ultimately, I found Direct Home Medical selling the same product as these other sites for one-half the price! I placed an order and received the charger which works perfectly. The entire transaction was hassle-free and I would highly recommend Direct Home Medical for any future purchases. Reviewed by: P Flores, New Orleans, La.
