Smoke detector and Carbon Monoxide detector

Be aware these items show they can be shipped in 2-4 weeks. that is not true, ordered mine over a month ago and keep being told they do not know when they will get them in. Instead of offering to refund your money they do not do that, you have to go after them to cancel the order to get a refund. Needless to say very disappointed in this company and take their review hype with a grain of salt. No better then ADT or other outfits.
