The other couplers I've tried are fine -- for one season. Then they tend not to fit together easily and the rubber hand grip falls apart. I like these couplers for their sturdiness and ease of connecting.
In our operation, we need to frequently change out hose combinations and nozzles. These do a very good job and are quite robust and durable. Another important feature is that they are repairable.
I have used plastic ones before and they don't hold up, so when I saw the brass ones I decided to try them. They are easy to use and are heavy enough to with stand frequent use and abuse. Good product!
Saves time and wet, frozen hands in winter when swapping hoses at the barn hydrant. Mostly works without a problem although the female connector can freeze up in very cold weather and will need a sharp tap to dislodge the ice.
Large capacity water flow, solid construction, reasonably priced. Plus continuous flow when disconnected.
I have everything good to say about this product. I cannot stand to uncouple hoses. I have many on drip systems and other sprinklers, water sources for chickens, dogs and horses. I have been using this product for about five years and add some each year. It is very sturdy and reliable and very fucnctional. I wouldn't think of ever have to go back to unscrewing a hose again. The only thing bad about the product is it gets dirty and is very hard to uncouple. After aging on a faucet or hose, or undoing a coupler many times a week, they age and are sometimes difficult to remove. A little WD-40 type produce usually solves the problem.
I have bought several of these (as well as the female one) and they have performed well for me. They don't leak and have held up over a wide range of temperature. They connect and disconnect easily and securely. Definitely worth the money.
The male/female hose connectors are fabulous! They allow full water flow, as opposed to my previous quick-connect couplers. They work perfectly and are attractive as well. I highly recommend them!! My son discovered them and we both love them.
