I have a few that are made completely of plastic. They are lightweight, but they only last a short time here in the Arizona sun. This hose splitter is heavier than others so I am hopeful this means it will last longer. This splitter does have some plastic parts on it, but it seems to be made better.
The on/off switches are much bigger than other splitters. This is really nice for my father (he's 82 and his fingers don't work as well as they used to). He can turn this one on and off without issue. The others, he can't, I have to come do it for him. With this one I don't. So the bigger on/off switch is wonderful.
You can get this item here on Amazon.
All in all I really like this hose splitter. It appears better made than others. It has bigger on/off switches. It just appears to be better than most others.
Have a great day!
