As seen in the pictures, the ATD itself is a small, black, flat disc that you attach to your wrist using a velcro strap. The Velcro strap is replaceable and comes in four different colors: Black, Blue, Pink and White. The strap is one-size.
Also included in the package is a travel case, a USB cable for charging and a printed version of the manual. Be aware that the charger plug must be plugged into a USB port on a computer, or into a USB charger that connects to an electrical outlet (not supplied).
You’ll find extra straps here if you want to have some in reserve – or just like having some colors to switch between.
If you want to customize the programs on your ATD, you will need to download a computer program found on this page . The guide to the program can be found in the manual that comes with it – which can also be downloaded on the same page as the program.
