Bests & Worsts Reviews from Amazon

I purchased this item in October of 2017 and I have used it for two winter seasons. Second season the lock "tumbler" froze and would not open with a key. I used a "key antifreeze/lube" to see if it would free the lock and enable the key to be turned. Nothing was working even after letting the lock set up with the lube and antifreeze injected into it. I needed to get the lock off and after trying all the keys I had for the lock quit trying. The lock appears to be a really "beefy" item and I anticipated it was going to be a challenge to either cut it off or pry it off. With the lock in the position "shown in the coupler" photo I slipped a crowbar between the inside of the lock and the coupler on the trailer. It didn't take me 15 SECONDS to remove the lock with just a little pressure on the bar. Pulling nails requires much more pressure. The item is JUNK! For the "would be thief" the bright red appearance of this lock would be a "screaming invitation" to steal this trailer...in this case an expensive Airstream!
