### ⭐⭐⭐⭐ Good, but Not Totaly Weather Proof
*by V***F on June 30, 2024*

Overall, these are excellent quality heavy duty Master brand locks. 3 of the four are flawless. 1 of the 4 the lack cover came off (didn’t stay on tight) during the winter. It got a litter corrosion in the lock mechaninsim, which really surprised me as it was after only a few weeks use outside on our snowmobile trailer door locks. As a result, the key for that one is tricky as it doesn't;t insert and turn smooth. If these had been used for years and this happened, i wouldn’t think too much of it. However, it happened after its first couple of weeks of use. Otherwise, the other 3 locks and their covers work perfectly. No problems and issue with them, so given the affordable price for 4 of them, I still feel good about the purchase. All in all, these are very heavy duty key style locks and I would absolutely buy them again for future uses.
