If you're a cautious driver in snow / ice you'll be fine. If you like to drive hard in hazardous conditions, a lunchbox locker isn't for you. Spend the extra $$$ and get a ARB. I'm running an Aussie locker in my yota axles connected to an auto trans, and I never notice it's there. It's locked when it needs to be, and unlocked when it doesn't... it's like magic.
