Someone tried my hotel door at midnight—LockWave didn't budge.

Took 30 sec to install and I finally slept soundly alone.

The hotel front desk gave someone else a key to my room by mistake. I heard their key turn in the lock, but the door didn't move an inch. The relief was instant. Never traveling without this again.

Stronger than my last 2 husbands

I’m so glad I packed LockWave. At 3 AM, a drunk stranger tried opening my hotel door — but it didn’t budge. This device is a travel must-have

So glad I had this!

Super easy to use and unbelievably effective. I set it up in seconds, and later that week the front desk accidentally gave a stranger my room key. Thank goodness I had LockWave in place — it kept the door shut tight

Easy to use and very effective

It takes 2 seconds to set up. Shortly after, the front desk gave a guest a key to my room by mistake. Thank god I had this, it jammed the door and would not allow it to open.
