Query: Software for device non-existant

Companion software (360 Management System) is non-existent. Whether you attempt to download it from Acc-chek home site, Amazon,etc. it is labeled "out of Stock" and has been for months. Not a beep about why, or how long. Stay away from anything labeled "Accu-chek. They claim to have latest tech (tanks, etc) but customer support is non existant. Buyer beware.
