I'm reviewing the Dramm 12353 Heavy-Duty Brass Shut-Off Valve and related connectors.
Despite the cons, I like this combination of fittings so well that I'm ordering a second set for another hose in a different area of my property.
Pros:
Heavy duty
Quality connections
Cons:
Shut valve is somewhat heavy compared to plastic alternatives
Higher price than plastic alternatives
The DGH7 Brass Quick Connect fitting contains a special rubber seal DGHW7 which is pricey online but not locally here.
I ordered these 3 items:
Dramm 12353 Heavy-Duty Brass Shut-Off Valve
Dixon DGH7 Brass Quick-Connect Fitting, Garden Hose Complete Set, 200 psi Pressure
Dixon DGH7P Brass Quick-Connect Fitting, Garden Hose Male Plug, 200 psi Pressure

Details:
Some reviewers warn that if you disconnect the male connector from the female quick connect while the hose is still under pressure and without using the shut off valve, you might blow the rubber seal out of the female quick connect. If you lose that rubber seal you can't replace it with a regular hose washer. The special seal DGHW7 can be pricey to buy online. I saw the rubber seal selling for $5.50 each plus $6.51 shipping! Locally, I paid 41 cents each at a local hose and rubber shop so I bought 10 seals! They piggybacked my order on another Dixon order so I paid no shipping costs.
The Good News:
It's been 18 months and I have not had to replace the special seal. I keep the shut off valve and female quick connect permanently attached to my garden hose outside in South Florida year around. When not in use, I keep a big ziploc bag over the connector tied off with a velcro strap to keep dirt and crud from getting in the connector. Sometimes I spray a little WD40 into the quick connect to make it work a little easier but its probably not necessary.

I ordered two of these valves, which are expensive. One of the valves failed to shut off the water and I only recently discovered why - that valve did not have the steel ball inside that controls water flow. There's no way it could have fallen out so it had to have come from the factory with that part missing. Not happy.

So initially I really liked these valves(bought a few) and although I had one fail I am a very happy customer. Heavy solid construction. The six sided hexagon shape makes it easy to tighten on with a wrench. I used:

LASCO 15-1731 3/4-Inch Brass Garden Hose Wye:
https://www.amazon.com/LASCO-15-1731-4-Inch-Brass-Garden/dp/B008E5CZLK

in conjunction with the valves because I wanted to go all brass. I like it too. After winter I gave the valve a twist and surprisingly I twisted the handle off. It felt like it was opening normally till the handle lay dismembered in my hand. I was a little gruff about this as the valves are pretty darn spendy.

Soooo I wrote Dramm on their website to get a replacement. Surprisingly I got a response in 1 day.

"Good morning Andrew,

If you can please send me your mailing address, I will mail you a handle repair kit for your Brass Shut-off Valve.

Thank you,
Amanda "

I gave Amanda my address and got the repair kit that same week. It came with great instructions which I didn't really need its so simple. Amanda didn't demand a purchase date, receipt, shipping fees, filling out a form, or sacrificing my first born. Just spectacular customer service.

Lastly to all the rookies complaining about leaking you should use some Rectorseal 25790:
https://www.amazon.com/Rectorseal-25793-No-5-Pipe-Sealant-1-3-4-Ounce/dp/B008A3U824

I put hoses on and leave them on year round and they never leak or fail. The gaskets on this valve will not fail and if they are falling out its because you are using it reverse oriented. Its designed for the male side to face out(threads out). The fact the number one reviewer can't figure this out and has let 7/10 fail astounds me. User error.

Like other have mentioned the white seal pops out and the the ball follows if your not careful. Wife is not careful and I'm the one looking in the grass for the parts.
Love that it is made in the USA. Would give 5 stars if it did not come apart. And I would buy more.

Great solid brass valve. After a series of Y-valve splitters that failed due to poor construction (and mostly plastic working parts) I switched to this all brass valve in conjunction with LASCO 15-1731 3/4-Inch Brass Garden Hose Wye. The resulting valve is solid brass, leak free and heavy duty, which is exactly what we needed.
