HoneywellLP550 E-Safe Electrical Plug Lockout

Works great but the padlock pictured does NOT come with it, though it looks like it does...

After I used it for a few times, I found out this cheap plastic box doesn't work. My son can easily take the wifi plug out of the cheap box and play computer games until 4 am. The hole for box is way way too big. This cheap box doesn't work. After I figure it out and contacted the seller, here is the reply I got :" Safety4Home & Work has closed the return request listed below.Reason for the closure of your request: Expiration of returns period."So please do not waste your money.
