Robinet de cuisine à 1 ou 3 trous à fixer sur le comptoir Kingston KB705

I've loved this for a few years. I would have given it a 5 but now it is very very hard to move it from side to side for the double sink. A plumber said that the insides may not be as protected from the water and mineral build up as other brands may have. I'm very sad as I may need to purchase a new faucet that won't be as nice as this one.
