VNEED Ultrasonic Pest Repeller, Electronic Pest Repellent [2018 Upgraded] Plug in - Insects Repellent - Repels Mice, Bed Bugs, Mosquitoes, Spiders - Human/Pet Safe (Round, 4 pcs)

This product does not work. I don't know it there isn't enough energy, sound etc... but the ants walk right past it like it's not even there. Absolutely does NOT work for small insects, mosquitoes, ants or flies!!

Only 3 stars.. Its kept the mice away so far but i also have all 4 in a 250ft area when they are rated for more than 1000ft area... - 3 stars because its not keeping any bugs away such as flys, spiders, or any other bugs away so....

Purchased these pest repellers to keep bugs in my apartment at bay and they were useless

Work great

This does not work as advertising says.Be aware this product does nothing for roaches, flies, spiders.I bought 8 of them for each room in the house and still roaches come from outside

Doesn't work for Mosquitos or mice!

Not sure if it works. Still using it no difference

These do not work at all
