Absolutely no problem with the equipment and the capability to do the job that it's intended for. I do however have an issue with the administration side of the initial setup. When it comes to registering emergency contact numbers it really falls short. Firstly there is supposed to be a form in the package when it arrives, there wasn't. No problem the leaflet states that this important task can be completed on line, having followed every possible link it became clear that this facility did not infact exist. So the only option left is to phone and request an emergency contact form be sent out, this necessitated speaking to three different individuals. Unnessesary complications to an otherwise efficient system.
