Red Sea Test Kits

I was wondering what everyone thinks of the Red Sea test kits.  They make a
"Deluxe Freshwater Complete Lab", that has everything one might ever want to
test for in a freshwater planted tank (pH, NH3 NH4, NO2, GH/KH, Fe, CO2, Cl2),
for a reasonable price (~$30), but I wondered about the accuracy, ease of use,
etc.  Anybody use this or have anecdotes one way or the other?

I'm nearing the end of getting everything together to set-up my 90 gallon,
hopefully it will be in the next 2 weeks, give or take a week or so.

Thanks -
