Review on 🪲 2 Pack Home Sentinel Ultrasonic Pest Repellent - Indoor 5-in-1 Pest Control Repeller with Electromagnetic, Ionizer, Auto Light | Effectively Repels Mosquitos, Rats, Spiders, and Rodents by Jamie Denison

I bought it a week ago and just arrived in my country, there are no instructions or similar material in the box. So I just plug one in and it just blows through! The current range in my country is 200V to 220V and I believe this thing is only 110V. My fault for not asking the seller before I connected it, is the seller to blame? Yes, 110V only is not specified in the product description. I connect another one with a voltage adapter and at least it works. So the light was on so I left it in the kitchen for the night. When I try to turn it off the next morning, a cockroach sits right on top of the device and it doesn't seem uncomfortable. So don't waste your money.
