QMOEH Drip Emitters + Support Stakes (50 + 50pcs) Perfect for 4mm / 7mm Tube, Adjustable 360 Degree Water Flow Drip Irrigation System for Flower Beds, Vegetable Gardens, Herbs Gardens.

I installed some this weekend. They were very hard to get on, until I tried dipping the hose in hot water for a few seconds. They then go on easily. I assume they will stay on because the barb is a little bigger. This is a plus since sometimes drip heads get pulled off by accident. They seem to work well. One thing I didn't notice before purchasing is they don't include an additional; connector to connect its tube to the main tube as some do. It is still a good deal.

These are SO HARD to install on 1/4 inch spaghetti tubing. Painful at best, melt-down frustrating at worst. The flare on the tip is just too significant. If I could go back in time I would not have bought them. Adjustment is also awkward, often all-or-nothing like other reviews say. One or two quickly got stuck where they will no longer adjust. Haven’t had these problems with other emitter brands. The one plus for these is they have an impressive throw radius, if attached to good pressure.

1/4" tubing does not fit around the attachments. I was able to squeeze a few of them on but it seriously stretched out the tubing and was very difficult to do. When they were finally connected, the water sort of dribbled out rather than spraying like it shows in the photos.It will only drip onto the spot that it is staked into the ground and will not spray at nearby plants.

Well I've just pulled put all my ofvit and idig brand sprayers as these ate better, I am very suprised especially for the price. I highly recommend these over either of those 2 other brandsSo much cheaper and does the same as orbit or idig brands. I will buy again.

Loved these over what was available locally

The emitters that worked were fine with a nicely adjustable spray at a very good price. Unfortunately about 1/3 of them were clogged and would not spray any water. Rather than return them all I found that I could use a small drill inserted in the end where the tubing connects, to drill out the blockage. Very poor quality control.

Do not buy. These barely work and the adjustment is essentially a full blown sprinkler with a huge radius or barely trickling. Nothing in between. The quality of these is terrible

I like the quantity quality and the price better than I expectedThanksGeorge
