We purchased our Oxyhelp chamber in September 2016. Before that, our company owned a Japanese model which didn’t work as we expected (there were recurrent small issues which prevented us from using it regularly). Before buying our new chamber from OxyHelp we were able to discuss all the questions that arised during our work with the previous one. The company owners were very understanding and treated our case individually with regard to all those problems we had with the previous chamber and to our particular (difficult at that time) situation. The staff was always there to answer our questions. In case we needed personal intervention (upgrading of our chamber) it was provided without delay. Besides that there were no problems with our chamber. It is reliable and never disappoints us.
