Metered Insecticide Fly Spray:
I have used automatic bug sprayers for my horses' stalls for many years. These are better made than the ones that I have used in the past. My horse even reached up 9' to chew on an old one and ruined the door. The larger canister seems to be lasting longer than the others would have, taking size difference into account. These may cost a little more, but, so far, I believe they are worth it.
"Bigger but NOT Better!"
"The first issue was the battery holder, what a knuckle buster! Then I had to call to find out what the setting ""D"" was for, as the printed instructions only went to ""C""!! :( And to top it off the spray can leaked all over the inside, and at almost $50.00 I can't afford that.... Oh, and just try to mount the bugger. Good luck!! I had to run hay string through the teenie tiny hole and hang it from a truss. Bad design...I will stick with my little ones until they perfect this one. "
