At this time, no program exists because we were designing / engineering / testingthe G2.5 unit (we wanted to give our customers a choice), and all G3 production is being used to fill initial demand. We will soon have the capacity to do upgrades and at that point, will announce the program.
To receive notification about the upgrade program, please email your name and phone number to G3.upgrades@iTroll.us.
Sending an email to this address reserves you a place in line when we offer upgrades. Note: The email address was made BEFORE we thought of making the G2.5. All responses to your email will give you a choice of upgrading to either a G2.5 or G3.
