When watering can I let myself be surprised. They served their purpose, with additional, not necessarily the usual details. The additional handle only acts a bit strange, even as an additional ballast. But if you have the can of and want to pour out at somewhat less favorable locations, so you can keep the pot better and better aim when casting. Or the side fill hole which makes depending on the design of the faucet filling easier because you do not get stuck with the Henkel at the tap after filling. The attachment can be rotated forwards, so you can choose between a normal metal stream or irrigation. This part is from me, because I personally do not need it.
The nice details may not be necessary for everyone, but you can simplify the summer garden work yet. Hence a buy recommendation!
