Review on 5800MINI Wireless Window Contact Honeywell by Franz Esquivel

I bought 23 of these 5800 mini sensors when I installed them, 9 of them don't work. To get ready I have to go into programming mode and exit *99 to return to ready mode. I've been installing Homeywell for 16 years now and I've never had any problems like this. This is the first time I install them with problems. I've never had a problem with the 5814 sensors they discontinued, they work great. I've been installing 5814 for years and never had such problems.
