EyezOff3.5" Carabiner Aluminum Multi Purpose Lock 4-Dial Combination D-Shape (Blue)

They work well, but one of them broke. The lever used to set the combo broke off. I was lucky I knew the code when it broke. No problem I'll just remember that combo when I use it. The other works flawlessly. I would buy them again.

Pretty flimsy. When you purchase a lock, it should feel like you can use it for what it's made for. I think this would not stand up to and force applied if it was going to be broken into.

Used to lock helmet to trike

Release button broken on arrival. Could be a good quality product if this issue was fixed.
