Nozzles exactly like this have been around for at least 40 years--manufactured in a dozen companies--and sold under a wide variety of brand names---for a very good reason---they are the best design.  They are perfectly and easily controllable, durable, and don't leak.  You can get "prettier" versions with plastic covers over the grip and plastic handles, if "pretty" is your priority---but, functionally speaking, you can't buy a better designed garden hose nozzle.
