I don't believe you would be able to use another
solution in the VersaPRO; the system checks for RFID chips in the
solution containers, and will not function unless they find them.
That said, Sunless Inc offers three different types of
solution options. We've always used the UltraPRO line, and have rarely had complaints. In fact, we frequently have clients switch from custom
airbrush to VersaPRO because they like the results better.
