Our club in Sacramento has TWO of these... the Chinese TT club 100 meters from our club has one too.
For what you get outta one (ease of setup, limited, but useful sequence, quick adjustable placement of system) you get a lot of value and performance for the price, even at is suggested MSRP price.
There is nothing on the market I know of that can do what this does with a setup and put into action time of seconds from bare table to go-live.
