the spray bottle works ok, you just need to keep pumping up the pressure regulray.
I wish they add included instructions on which nozzles to use for which different solutions you use.
But I do feel i was inundated with emails before and especially after buying.
I also feel a little bit let down that Hydro announced a newer version of the spray bottle, just after I purchased mine, it seems like they was trying to get rid of all the older spray bottles.
But my spray bottle works well
