KärcherPremium Oscillating Sprinkler - OS 5.320SV, Black

Great build quality and ample settings: have to move twice to cover my lawn, but so much better than previous sprinklers. Excellent.

Works great and even with low water pressure

This sprinkler is fantastic. That's all I can really say about it. Extremely easy to use out of the gate, and everything it says on the tin and the advertisement blurb works as intended - a rarity in this day and age for sure!Karcher has gotten a bit of a reputation for slowly "downscaling" their quality over time, some of their products you bought 10 years ago when bought again today have certain fittings replaced or altered which are less effective / durable than their ancient counterparts, but that doesn't seem to be the case here, thankfully.I haven't measured my garden, but I have a 40m hose that runs out of length about 90% down the garden, so my garden must be around 50m or so. This sprinkler gets it all when put in the middle and set to the maximum power and spread distance. It sprays all the way to the bottom hedgerow and all the way to the upper grow boxes on the patio. That's pretty amazing stuff, considering I live in a fairly low pressure area and I'm using it from the outside tap too. When I use the hose without a nozzle it's a big ol' fat spray of water, not a jet, that kind of level of pressure, you understand. This sprinkler is an excellent pressure multipler then.I wish I could calculate how much water this thing puts out per hour or whatever, but I'm not anywhere near smart enough to do that. I will say however that leaving this thing running for 30 minutes makes my entire garden look like the heavens opened recently and we got a light shower. Very nice indeed!The only complaint I can think of is how wide the spray is, it easily reaches over the neighbours garden on either side - but you can just turn off nozzles with an easy button press and that problem is instantly solved. The other only plausible issue is the fact the cleaning pin is really annoying to unlock and remove, but I imagine this is a safety feature so your children don't end up gouging each others brains out or something with it. Using a butter knife, a coin, your shed key, anything that's strong, sturdy and thin enough to slot into the gap and twist it to unlock it, it easily pops out. Really tricky by hand though.If you've got an interest in watering your poor, beaten, dry and brown lawn and maybe resuscitating it to a verdant and lush bounty, you'll want to buy this water sprinkler. It's absolutely fantastic.Don't forget the white clover!

Does what I expected it to do

I’ve been debating whether to get a sprinkler for our garden for some time. We have got a reasonable sized couple of lawns, in total about 60m x 7m which are often in a pretty poor state due to moss and over hanging trees, along with a resident collection of squirrels, foxes and avians digging the place up. However, after conducting an extensive lawn repair I felt time was right to get a sprinkler to help keep the grass hydrated while the new seeds are growing. I looked at many sprinklers, and didn’t mind spending a bit of money to get the right one. The main choices tend to be by Hozelock, and they have a considerable choice on offer, however the reviews of them are always just average so I’d put off buying one. Then I happened to stumble across the Karcher sprinkler on Amazon, listed as £15 for Prime members reduced from a £39.99 RRP. The reviews were much better on average than any of the Hozelock products, and there were plenty of reviews to look at showing it was actually quite popular. I have to admit I didn’t even know Karcher did sprinklers…..and I own their pressure washers and window vacs so I’m no stranger to them.The sprinkler is impressively well built and is certainly a chunky product. It is also easily configurable to meet your garden’s needs, which I wasn’t expecting. There are banks of jets pointing in different directions laterally, each of which can be individually turned on or off. Likewise, there are slider controls allowing you to customise how much the sprinkler oscilates in either direction. This is great as you can effectively prevent an area from getting wet, such as on my front lawn where I could stop it from showering passing pedestrians from getting soaked. There is also a slider control to adjust the amount of water coming out, with the ability to turn it off completely. Finally, there is a “patent pending” piece of plastic that rotates around from the side which blanks off the half of the sprinkler closest to you, allowing you to adjust the direction and power of the jets on the other half without you getting a face full of water while you do so. All very well thought out. Naturally, it connects to Hozelock attachments, given they seem to be the industry standard.I was conscious of our relatively low water pressure (the sort where if two taps are turned on together you end up with a pathetic dribble) and what impact it would have on the performance of the sprinkler. It easily covers the 7m width of the garden and oscillates to a coverage of 8-9m. It means that on my particular lawn with my water pressure I need to move it a few times to give total coverage, but it’s so much easier than wandering over the whole lawn myself.It has impressive features, is very well built and does an excellent job despite the poor service provide for it. I think I’ve made the right purchase.

We purchased this to help manage our grass growing efforts and the need to keep it well watered. We liked the features hence was willing to pay more for it.It was very easy to snap on/snap off with our hoze pipe connector and can quickly interchange it with the spray head which we use on specific sections of our garden.The sprinkler allows easy and watering, covering specific areas of the garden and omitting other areas if you need either by limiting the arc of the watering, or turning off specific sections. We have used both options extensively when watering as we place the sprinkler in 2 - 3 different sections of the garden to ensure coverage, and turn off sections to not-overwater the same areas.And because we manually move it around, it is also super useful that you can turn off the water flow from the sprinkler itself versus having to turn it off at the faucet. you could also use the protector lever but we found that it is really just easier turning the flow valve off/down.With regards to water flow, it is dependent on what you get from the mains. On a normal day, it works very well and has a strong flow of water. When both kids are showering and the dishwasher is running, it does affect the water coming out but not so much that it would cause a complaint.Overall we are very happy with the sprinkler, the robust quality, and the easy to use features.
