4.5 6000 PSI Turbo Laser Power Pressure Washer Rotating Nozzle 1/4" Inlet

Is this one fatter and heavier than others on the market? In other words, is the rotation angle greater than the others?

Do these have any type of warranty? I bought one on January 25th 2016 (2 months ago) and it's already gone bad. I even run a filter on it

Can i use this with a 3200 psi washer?

Will this work with a 5.5 from 3500 psi machine
