Quick verdict
A 60-piece bag of pressure compensating drippers in 0.5, 1 and 2 GPH, rated to hold flow steady between 10 and 60 PSI, with a self-cleaning diaphragm and barbs that push into 1/4 inch line or a punched 1/2 inch mainline. For a mixed bed of pots, shrubs and vegetables it is the convenient way to get three flow rates without buying three bags. The brand is unknown, so treat the ratings as nominal.
Strengths
- Three flow rates in one kit: 20 each of 0.5, 1 and 2 GPH
- Pressure compensating from 10 to 60 PSI keeps flow even along long runs and on slopes
- Self-cleaning diaphragm resists the grit that clogs cheap drippers
- POM plastic resists UV, heat and fertiliser
- Standard barb fits 1/4 inch tubing or a punched 1/2 inch line
Weaknesses
- Unbranded import; long-term consistency between batches is unknown
- Colour coding of flow rates is easy to lose track of once installed
- No flag or stake included; buy stakes separately

Why Pressure Compensation Matters in a Home Drip System
Most drip problems come from uneven pressure. The first emitter on a line sees more pressure than the last, so the near plants drown while the far ones dry out, and a slope makes it worse. Pressure compensating emitters solve that with a diaphragm that narrows as pressure rises, delivering close to their rated flow anywhere between about 10 and 60 PSI. FUNCSDIK’s 60-piece kit bundles 20 each of 0.5, 1 and 2 GPH compensating emitters in one bag, which is the practical way to equip a mixed garden.
This review is based on the listing specifications and on how pressure compensating emitters of this design behave in general use. We have not run these emitters ourselves, and the brand is a generic importer without a long track record.
What You Get
Sixty emitters split evenly across three flow rates, each with a standard barb that pushes into the end of 1/4 inch distribution tubing or directly into a hole punched in 1/2 inch mainline. The body is POM plastic, a hard engineering polymer that shrugs off UV, heat and fertiliser salts better than the cheap polyethylene used in bargain drippers. Each emitter carries a self-cleaning diaphragm that flexes to pass small particles rather than trapping them.
Flow Rates in Practice
Having three rates on hand lets you match water to the plant. Half a gallon per hour suits small pots and drought-tolerant plants, 1 GPH is the workhorse for vegetables and perennials, and 2 GPH feeds shrubs and large containers. Because every emitter compensates, you can mix rates along one line and each plant still gets what its emitter promises, which is impossible with non-compensating drippers on a long or sloped run.
Installation
For pots and beds, run 1/4 inch tubing from a punched mainline and push the emitter into the end, then hold it in place with a stake. For direct insertion, a drip punch makes a clean 1/4 inch hole in 1/2 inch tubing and the barb seats with firm thumb pressure. A screen filter and a pressure regulator at the tap remain essential; compensation handles variation, not debris or 80 PSI house pressure.
Reliability Considerations
Generic drip hardware varies by batch. The design here is sound and the material choice is good, but there is no brand warranty history to lean on. Owners of similar generic PC emitters report the main failure is a stuck diaphragm after a season of hard water, which a soak in vinegar usually frees. Buying a few spares, which this 60-count makes easy, covers the odd dud.
Who Should Buy It
- Gardeners with mixed plantings who need several flow rates on one system.
- Sloped or long runs where non-compensating drippers water unevenly.
- Anyone expanding an existing 1/4 inch or 1/2 inch drip system cheaply.
Common Owner Complaints
With generic emitters the recurring notes are a few units that flow slow or not at all out of the bag, confusion over which colour is which rate once installed, and clogging where no filter was used. Labelling lines as you install them and fitting a filter addresses two of the three.
Alternatives to Consider
Rain Bird and DIG sell branded pressure compensating emitters with published performance data at a higher price per unit. Adjustable drippers suit people who prefer to tune flow by hand. For a complete raised bed system, a kit such as the GGAQHLK 230-foot set includes emitters, tubing and fittings together.
Verdict
For the price of a single branded 25-pack you get 60 compensating emitters in three rates, built from the right plastic with a self-cleaning diaphragm. Use a filter and regulator, label your lines and keep a few spares, and this kit will water a mixed garden evenly for seasons.

FUNCSDIK 60-Piece Pressure Compensating Drip Emitters (0.5, 1 and 2 GPH) FAQs
A flexible diaphragm inside the emitter narrows as pressure rises, so an emitter at the top of a slope or the start of a run delivers about the same flow as one at the far end. Non-compensating drippers deliver more water where pressure is higher.
Roughly 0.5 GPH for small pots and succulents, 1 GPH for most vegetables and perennials, 2 GPH for shrubs and large containers. Soil type and sun matter, so adjust after watching the first week.
Yes. Any drip system needs a screen filter at the source, typically 120 to 155 mesh. Self-cleaning emitters tolerate fine particles but not sand or scale.
Yes, through a hole made with a drip punch. For pots, run 1/4 inch tubing from the mainline and push the emitter into the end.
