This garden hose spray nozzle is advertised as a water saving nozzle with seven flow setting, and that is exactly what we found it to be. The plastic and rubber grip construction of this nozzle is very comfortable in the hand, and makes the unit great for your light duty garden, patio and car washing needs.This nozzle was easy to install on our garden hose (Water Hose Goodyear " x 50' BLACK RUBBER Industrial 200psi with Brass Fittings - Heavy Duty - USA), though we recommend a little caution when putting it onto you hose. We suggest that you tighten until just firmly snugged into place, as over-tightening onto the hose's brass fitting could crack the nozzle's plastic fitting. Tighten until just firmly snug; don't ape tighten it!The spray settings dial needs a firm twist to move from setting to setting, but it is easy to move once you get the hang of it and there is a very loud audible "click" when you properly move to the next setting. The settings worked as noted (Flat, Center, Cone, Full, Mist, Jet, and Shower). I like Full and Jet for car washing, and Shower for garden plant watering. This spray nozzle does seem to manage water flow as intended; it does not produce the stronger jet of the different units we have, but it does not produce the weakest either. Seems just about right for what it is intended to do.While seemingly not a nozzle that a commercial irrigation crew would carry on the job, it should be right at home when used for light duty household job. Simple to use and effective.The Amazon sales page notes that Pretmanns does "guarantee it for a full year against any defects in material and workmanship"; however, the nozzle's package clarifies that guarantee by confirming the timeline and further noting that a "$3.50 fee will be charged for postage and handling". If an issue arises before the guarantee period expires, I will return here to update the review and let you know what the issue was and how resolution was handled. We did receive this product gratis from the manufacturer and have put it through the paces to objectively find out how well it performed. My statements here reflect that testing.If looking for a garden hose spray nozzle of this type, style, and construction, for use as described above, then we recommend this one based on our experience with it.Go for it.
