    Very easy to use and seems very sturdy. I especially like that it comes with a locking pin in addition to the spring loaded button to lock it in place.

    My husband had been looking for door hammers at various doors, but didn't find a satisfying type. I came across this door jammer on Smarthome website, and took a chance ordering 4 to get free shipping. We are happy with the good quality and low price from Smarthome which price is even lower than from Walmart.
    ROBERT -- davie, FL   7/1/2013
    I love you product.
    ROBERT -- davie, FL   6/24/2013
    I love this product. Thank you.
    MARY -- dandridge, TN   6/13/2013
    I purchased this for my granddaughter's apartment front door. It works great, the stem is tight so if anyone kicks at the door, it can hold up & not slip out of its peg slot (for the height of the stem I mean). This allows her to sleep in peace when her fiancé is working an occasional night away from home. I can sleep too know that she's safe with this door jam in place. Thanks!
    JEROME -- warren, MI   4/28/2013
    A very good product at a reasonable price. I bought 3, two for home use, 1 for my granddaughter in college.
    LYNNE -- warren, MI   4/18/2013
    Works as advertised. I use it every night for my apartment door just to be safe.
    JACQUELINE -- cypress, TX   3/18/2013
    I was pleasantly surprised at how sturdy these door braces are and how fast I received them.
    NANCY -- tabor city, NC   1/31/2013
    Added security for the home. Tested by family member who has a kick force of 600 lbs+ and he could not dislodge the door brace - hooeeee! can sleep better at night. Thank you for this product.
    WENDY -- mt. washington, KY   12/12/2012

    This was the second Big Jammer I had ordered from your company. Great product and great service.
    CHERYL -- centerville, UT   5/9/2012
    I LOVE the safety I feel from having this product. I love it so much that I gave one to my parents for use in their second home in another distant county.
