Really good product for the price. I have them on all my trailers. They hold up to the elements well and I’ve never had issues with them freezing up during the Alaskan winters. I accidentally lost the keys to one and had to cut it off with a grinder wheel. Took me about 15 seconds to cut through it but there’s not many tongue locks out there that can withstand a grinder and certainly none for this price. I doubt a bolt cutter could make it through without serious effort. Having a big yellow lock on the front of your trailer is definitely a good deterrent.
