Notekeeping Calculator with bluetooth and other special features

I have 3 x Ruby Devices Note Keeping scientific calculators. these calculators function as regular scientifc calculators but also have the ability for you to store long elaborate notes on. They connect to your phone or tablet via bluetooth to allow for notes transfer. i have 2 x of the older model, which allows for a single line of note reading at a time. The one has the coating on the screen peeling otherwise the functionality is still perfect. then i have 1 x of the ultimate version that has multi line screen reading. It can also do instant messaging between itself and a device it is connected to over bluetooth and it can also google search. see rubydevices.com.au for more information. pricing 1 x old model with peeling screen R1000 1 x old model in perfect comdition R2000 1 x latest model in perfect comditon R2700
