I have the Scala Q2. If you are going with the Scala, I would also recommend you go with the G4. I had the Q2 for two seasons and at the end of last season, once the units were turned on, it actually took a 1/2 before they started working. This happened about 4 times after both units were charged.
I believe it was baja ron that pointed out the Scala Q2 with the orange dot/emblem was noted for having problems. So, if by chance you want a Scala Q2, make sure it is with the blue emblem, not orange.
I had the Q2 before the G4....G4 is really quite an upgrade...better in all ways...plus, those online updates are really great! They can address any issues users might have...
