Automatic Air Freshener Dispenser Wall Mounted Auto Spray Dispenser Aerosol Spray Dispenser Programmable Fragrance Dispenser (LCD panel)

I use four of them in my condo

I initially thought these would be great alternatives to the cheap dispensers that you can buy in the stores, with the cans of scent, but they are just a step above, with buttons to program inside, and an intentional plastic "lock" with a plastic key, which is absolutely useless, because you cannot open it after you lock it, the key just goes around and around and around, and there is no way to get the lock out, unless you use a sharp object, when the two dots are aligned and pry it out. I purchased three of these and one seems to work fine, but the 2nd one had the problem noted above and I don't seem to ever witness it spraying. The 3rd one is yet to be tried, because I want to make sure that this 2nd one, after it took me hours to figure out how to open it, after I stupidly locked it, before finding out if it worked, works. I may send the two back to the Seller, if I cannot get them to work properly. (One out of three doesn't seem like a good ratio, but honestly, I haven't tried the 3rd one yet.) I personally hate the weird greenish color. I wish it was black, like the same model that is a remote control unit (which also doesn't seem to work, with the remote, other than to turn it on and off.)

This fragrance spray is probably good but very complicated to set up, it takes too much time to set the days, hours and intervals to spray. The instructions are ok but the system needed to be a bit simpler to set up.

These things are completely worthless. I bought 2. HUGE mistake. Neither of them do the spray can's fit properly despite being advertised as being able to fit. One device just makes loud gear grinding noises when trying to spray. The other one has no strength at all and won't spray because it can't even push down the spray nozzle. WASTE OF MONEY.
