Product review (5 stars): Much better quality than rubber hoses.
Bought to replace the original rubber hoses which had developed a leak.  These should last the lifetime of several washing machines.
The right-angled end goes in the back of the machine to allow you to push the machine closer to the wall, but you can connect the right-angled end to the wall outlet if you have recessed outlets with not enough space to bend these hoses (they're less flexible than rubber ones).  You just won't be able to push the machine as close to the wall.
I would recommendeveryyone replaces their rubber hoses with metal ones.  Do it before your rubber ones leak, which they will do.  Better to spend a few dollars now than have the cost and inconvenience of water damage.
