Gardena20570, Up to 3800 sq ft - AquaZoom Adjustable Oscillating Yard Sprinkler, for Watering Large Area Lawn and Garden. Aquazoom Outdoor oscillating Sprinkler has Wide Heavy Duty Base.

The sprinkler looks, works and is built great -- I like that the oscillating barrel part is straight across and supported with two Stainless rods that run end to end -- there is only a quick connect option (included) I don't believe that you can just screw your hose on to it -- the ones I had years ago were in an arch -- this is supposed to cover 55' max width -- with my water pressure ( 50 PSI) it only covers 35' width (I need 50') and 25' from center to reversing which is perfect for my small yard -- this has everything I would engineer into it -- the tube moves quickly -- not quite enough time to run in and change a setting without getting wet -- I have it placed in front of my shrubs at the front of my house pointed to the street -- neither line is straight so some compromising happened -- I buried these in some 2"~3" River Rock with just the top peaking out making sure none of the rocks could touch the barrel -- it runs smoothly and quietly -- I had two round sprinklers that could be adjusted to hit odd angles (they had 15 separate adjustments and are not available anymore) -- they worked great mechanically but did not water evenly -- I got tired of trying to use round sprinklers to water a rectangular area -- originally I was trying to avoid this type of sprinkler that shoots water in the air and gets blown by the wind but now I believe that if I water early there isn't as much wind -- I have two, one in front and one in the back that are on a timer set to water at 5:30 AM -- the color blends into the shrubs and stones and can't be seen from the street -- I am really happy with this setup and hope that I have shared an idea that you haven't thought of -- no fusing with pop ups or broken pipes -- for under $175.00 all in I have a permanent above ground system that is worry free (no issues with the lawn mower) and maintenance free -- they can't be easily seen -- no one would suspect that this type of sprinkler would be hidden this way -- I wanted the larger one that isn't currently available but maybe I can get the coverage I need by increasing my water pressure

Like many have said it is a great sprinkler. (One word of advice at the end.) Bought it summer of ‘15. I don’t always need to use a sprinkler but when I do I pass up all the Mickey Mouse ones and head straight for this one - Always! (no offense MM). Still works perfectly. No electronics. No batteries. Everything manual. Nothing to rust. VERY easy to set and modify if necessary. Nice even rectangle so no need to water some areas 4 times to get other areas once. Covers an amazing area. One caution. I by no means treat mine with kid gloves but I don’t abuse it either. It is plastic. Plastic has it pluses and it has drawbacks. Common sense should tell you that it does break if treated roughly. If you have kids that ride their bikes over the sprinkler, and hubby throws it on the cement patio every week when he mows the lawn, and the neighbor kid uses it in the street as a football, then, yes, my advice would be to stick to a very simple metal one - like the old owl-eye. Most of you moms and wives know exactly what I mean.

This is an outstanding product. It is very well constructed, and thoroughly engineered in terms of it's design and performance. In addition to having an extremely large coverage capacity, the variability of both the coverage length and coverage width is so broad, it should accommodate almost any yard configuration.On the downside, it is very expensive for a lawn sprinkler. But in this case, it is certainly a product that is well worth the extra expense. But you do get what you pay for. So if you want to treat yourself to an exceptional product, pay a little more for this sprinkler. Because you get a lot in return.Highly recommended.

2013 Update: This sprinkler was purchased in 2011. I am using it for the third season. How has thisunit stood up? Not as hoped. It has now begun to not rotate as designed. Sometimes it sticks in oneposition or the other and sprays all the water in one spot. I've tried to get it working properly which sometimes it does cooperate, but sometimes not. It is unreliable. I attribute it to the plastic construction since I have another rotating sprinkler made by another mfg which is completely metal and it has worked flawlessly for years.Another problem that has surfaced is the quick disconnect. Sometimes when connecting the hose to the sprinkler, the connection does not allow water to pass through the connector to the sprinkler. There is a self-sealing valve in the connecter that prevents water from gushing out the end of hose if sprinkler is not plugged in. This valve is supposed to open when plugging to the sprinkler. Many times it does not open and no water gets to sprinkler. You have to keep fiddling with the contraption until it decides to cooperate. Again, probably the plastic construction.The Gardena is NOT worth the money because the German engineering acts more Chinese. I will use it the remainder of this summer, then relegate it to the pile of products that made promises they could not keep after the warranty ran out.Original Review (2011) The Gardena 1975 was purchased because of its reputation, good reviews and large square foot spec. I was tired of moving sprinklers and this one held out the promise to cover my entire front lawn from a single position. I measured the lawn to make sure it was within the 3800 sq. ft.Like most products nowadays, the Gardena is not the ultimate in design, quality, or performance and shows signs of using cheaper materials to keep down the price. The product has good and bad points.The good: Seems well made from a precision stand point. It can be adjusted in four directions; forward, back, left, and right. There are four levers that easily accomplish these adjustments. It has a wire mesh filter to keep any trash in the hose out of the unit. The quick connect is a great feature and doesn't leak. The unit reverses the sprinkle cycle quickly with minimum linger time when it reaches the limits of the forward and back direction.I do wish engineers would discover a way for these types of sprinklers to lay down a perfect rectangular pattern. Instead, they round the corners as they complete the forward/back cycle. That always leave four spots that don't get the water.The bad: Made from plastic including the quick connect, thus Gardena guarantees the product for only 2 years. It does not appear to be flimsy toy plastic, so maybe it is more like industrial plastic. The sun probably won't do its damage in two years, but will surely shorten its life compared to an all metal sprinkler.Because this unit is plastic, it is very light. That means it doesn't always want to hold the position in which it is placed when working at the limits of a garden hose. With a hose of sufficient length to have some slack, this isn't a problem.The biggest disappointment is the coverage. If you read the specs closely, they say UP TO 3800 square feet coverage. The UP TO figure is a deceptive way of making a claim for a product which you are likely NOT to achieve. If manufactures wanted to be truthful, they would give the consumer an "average" figure which would be more realistic. I expect if your local fire department hooked this sprinkler up to their pumper truck, you might get 3800 sq. ft.; otherwise, be realistic (think 2500 or less s/f) when making this purchase.Water pressure and hose diameter all contribute to the coverage being less. In my case, with average residential water pressure, I get less that half the coverage they advertise and am still moving a sprinkler around to cover entire yard.I do suggest using a 3/4" diameter hose with this unit to improve coverage. The larger diameter allows more water flow, thus larger coverage.Do I recommend this unit? I'm on the fence. It was overly expensive, yet did not deliver what I expected. I don't have the satisfying feeling that I got my money's worth. For less money I have a similar sprinkler from another mfg. made entirely of metal and wets almost as large an area. My guess is, it will outlast the Gardena even without German engineering.
