The supply lines are aweful and wanted to twist up and kink while connection to the shut-off valves. Then once installed they leaked because there were no o'rings/rubber gaskets installed into them and no they were not in the packaging. The faucet is beautiful but if it leaks and it takes way longer to install because the supply lines want to bind up and kink during installation because they are very thin. The rest of the product seems to be well made and I hope to enjoy it for years to come once I get the o'rings sent to me.
