Pros - Easy setup, maintenance free, hassle free watering
Cons - You have to buy an adapter to mount it to a standard water hose.
I was tired of having to take the usual hanging waterer to refill it a couple of times a day so I looked into automatic systems. This is much easier to setup and cheaper to buy ($25 on Amazon) than the usual nipple systems.
I bought a $5 adapter to connect it to a water hose and hung it in the coop. It was easy and the birds took to it immediately.
It is easy to adjust the water level, easy to clean and is worry free. I highly recommend it.
Pros - base is strong material and real copper
Cons - your flock could end up dehydrated
This was an expensive mistake. It was such a good design to provide clean, fresh water for our flock. However, the way the hose attached wasn't practical. They didn't figure out how to use it.
