When they used to send us the drivers and let us fix them, it was OK. Now we have to pull them and ship them back. That really sucks. Even worse than fixing them in the field. At least when we fixed them in the field, it was only one trip to the house. Now it's no sound for weeks...

We've almost completely stopped selling rocks altogether. Now we sell black boxes on stakes. We can always find a spot in the landscaping that hides them, and they sound better and last longer.

Another plus... No BUGS!
