This product is junk plain and simple. I have had it for less than a year and it is garbage. With in the first couple uses the lock and the switch for different spray positions wouldn't work. I have to manually switch it to the position I want. I needed the locking position due to my arthritis and it just won't lock into place. I just now noticed that the screw in the center of the nozzle is rusting away. What a waste. I recommend paying more money for a quality sprayer as I will now end up doing.
