Faulty Faucet

My toilet's faucet is broken yesterday so we had to buy a new one.The old one has been leaking for the past few weeks untill one day,it could not be close.SO the water main have to be shut down for a while and then we replace the faucet with a shower head for the time being.Looks wierd.So today we bought a new one to replace the old one.It was much heavier and shinier.But the nozzle looks more flat.
