Query: what a rip-off!!!

Great idea and good price....IF it worked!! Tried everything to get this to lock when I got it to no avail. Unfortunately I paid for 2 day shipping on it as well. So even though I am returning the product for refund, I lost out on the $24 shipping. SAVE your money and get a brand name product not this piece of junk!!!
