This is a very well built metal sprayer.  It holds the pressure well and the nozzles and O rings seal the tips perfectly for an even spray.  It is a little pricey but there is no comparison with this sprayer and those plastic ones you see in the big box store.  This sprayer can handle harsh chemicals and just about anything else the normal homeowner will need to spray around the house.  The adjustment nozzles have a great range so you can spray back in those deep corners from a good distance or set it to fan and get the up close spots without it leaking all over the place or on you.  The unit is well sealed for leakage at the wand end.  There is a bit of a learning curve on using this sprayer - the top seals in a different way so read the directions before you fill it up so you won't get a face full of chemicals.  Amazon shipping etc. was good as usual - they are the best.
