Airofit PRO Breathing Trainer

Only works for a short time – This product has a faulty e-unit (battery) that when not used for a few weeks to a few months it fails to charge again. The manufacturer and the Australian retailer never respond to requests to sort this in any way. In fact, search for this product on Amazon and other places and you will see that many others have problems with this model too. The have since dropped that model and have a new model 2.0, but no trade-in or discount is offered to those who have the dodgy model 1.0.
