25 Pcs Drip Irrigation Emitters, Adjustable Flow 0-18 GPH Irrigation Drippers with Stake, 360 Degree Flow Sprinkler Head, Micro Sprinkler for Garden Patio Lawn Flower Bed

I put two sprinkler heads into each flower box. I have 12 boxes that go along a railing in the backyard. Very effective and keeps plants watered all the time sprinkler automatically comes on twice a day for one to two minutes.

Excellent micro sprayers. Almost didn’t buy due to the many negative comments regarding how hard it is to slip on the tubing. The cost was so low I decided to give them a try. They definitely have a larger flange than the Rainbird sprays and will not go on without dipping in hot water. But do that and they slide on like butter. I just poured boiling water into my Yeti mug and it stayed hot enough to install sprayers for about 15 min.

Great price. Seem to work well. Have to push very hard to get connectors on the tube.

it is easy to install。

They look just like Mr. Landscaper, but looks are deciving. That's the only thing they have in common, the plastic is brittle at best, the barb is too big for 1/4" or 4mm and the best for last. The top ajustment nob has no detents to keep settings. So after 6-7 cycles from the timmer the flow increases from the water hammer. This floods some of your plants and from drop in water presure some go completly dry. This is what happens when your brick and morter is out of stock, Chinese junk. Sending them back, it's not about the price.

After three tries Amazon finally delivered the right one.One head has already failed only after 3 days. Either it delivering a trickle of water or a very weak stream. Pulled the head off of the tubing to verify there was no dirt and the tube.Have a disc filter on the irrigation system so it wasn't anything from the water supply.Compared to the adjustable bubblers that were there before the holes in these are a little too small making the Stream shoot out farther.This is actually counterproductive for my application where we have put in Earth rings to hold in the water.Adjustment is very tricky 1/8 to 1/4 turn no spray to large spray. Had to barely touch it to get the strain to be where I wanted it so it wouldn't undermine the soil ring.The barbs on this are oversized and very difficult to get onto quarter inch tubing. They have this little illustration saying to dip the tubing into hot water for a few seconds but I only saw that afterwards.It really takes effort to be able to get the Barb in without first Heating the tubing. But I was putting this on Old tubing and it was already and the high 90s outside.It took some effort to get the tubing on the Barb. It split one tube and I had to cut it off and start over again.I would suggest using a Phillips screwdriver or circular wedge to expand the end to get it on to the fitting.

Work great & very sturdy

These are so nice as the spike keeps them in my pots AND I can adjust the flow so easily.
