The system is still working fine. Extremely pleased with this monitor
Actually the technology has not changed or there is no product enhancement in last 7 years since my first set. Installation is a breeze and a double sided tape does the trick, no screws. Position the sensor at least with 1/8" ground clearance, so the unit does not actually hit the concrete slab in the garage, especially if using screw mount, as you will definitely crack the mounting holes, without this precaution.
Do not position the main receiver behind too many walls, the signal will just not penetrate and will attenuate through lot of walls and obstructions. Remember radio waves do not bend around corners.
Best position is at a central part of the house where all units can transmit equally to a mid positioned receiver.
Battery life is good but to preserve the signal strength needs a default replacement every year. The main unit blinks when the battery gets low. No complaints so for, these units have worked great and would recommend this as an essential, if you fear your garage doors going up in the middle of the night.
Once you have these installed it is difficult to be without them. They do a great job!
I couldn't not seem to get all three units to work all the time no matter where I placed either the sensors or the receiver.
I also couldn't get in contact with the Skylink company for assitance. Lou
