The products and services were very good.
JOE -- austin, TX   7/8/2011
My original window contacts were quite old and malfunctioning in the middle of the night giving the security system a false alarm. The contacts (magnetic switches) are perfect replacements and work as advertized. I would recommend Smarthome without reservation. Shipment was fast and properly protected. Joe E

Good mini-contacts, good for replacement door and window alarms.
JESSE A -- hayward, CA   9/12/2010
Excellent product and transaction. My old ones were falling apart and the juvenile cats destroyed a couple. These are so powerful yet so inexpensive. Definitely will buy from again. Thanks!
LUTHER -- miami, FL   6/11/2010
The contacts worked great so far,I just would prefer if the magnet side was all white with the magmet not visible.
HECTOR -- interlachen, FL   3/13/2010

There was a problem in my order, but they went far out of their way to correct it. I would have no problem ordering again from them.
