Review on 🦟 Jmxu's 40W Electric Bug Zapper: Powerful Mosquito Killer for Indoor, Backyard, Patio - Effective Insect Fly Traps with Electric Shock Grid and Mosquito Light Bulb by Brenda Finlinson

So this is a solid standard example of your standard indoor insect killer. It's a simple on/off switch and when it's dark inside a few flies will flock to it. This is a standard light bait so its effectiveness is usually low in daylight and of course at night it depends on where it is placed. The lower the worse, the eye level is better, it's nothing special so I'd call it a solid 4 star buy. Just my thoughts, a.k
