I brought the Nitecore EMR06 TAC Electronic Mosquito Repellent with me and my dog to the park over the weekend, and it worked really well. I noticed far fewer mosquitoes around us, which made our time outdoors much more comfortable. It’s compact, convenient, and easy to carry. Highly recommended for pet owners and anyone who enjoys spending time outside!
Small and handy
I purchased the EMR product for the second time because of the excellent experience we had with the EMR 16. My son is usually very susceptible to mosquito bites, so we decided to let him use it during his Primary 5 camp. He used it throughout the night, and to our surprise, he returned home without a single mosquito bite. The product performed exceptionally well and gave us great peace of mind. Based on our experience, this is an excellent product that truly works, and I would highly recommend it to others.
I love it. It keeps the mosquitoes away that I bought 2 boxes at one go. No buzzing no bites. Nitecore Mosquito repellant mats keeps them away.
Works well, helped to repel mosquitoes outdoors. Trustable brand, worth to buy. Device is also lightweight
Speedy delivery, i was struggling with which insect repellent device and seeing the positive reviews decided to gave this a shot. Hope it works

Love the long battery life without having to worry about recharging for long walks or hikes.
I was hyped about the product but after trying it for 1 day, I was disappointed. The runtime does not last for 10 hours as claimed.
I’ve been using the EMR40 with a mosquito repellent mat and I’m very satisfied with it. It’s easy to carry, has great battery life, and does an excellent job keeping mosquitoes away during my morning and evening dog walks at the park.
“I’ve been using this mosquito repellent mat with my EMR40, and it works very well. It effectively keeps mosquitoes away when I walk my dog at the park every morning and evening.
My son's blood is tasty to mosquitoes. So he is suffering in camp. But after using the Nitecore EMR40 Electronic Mosquito Repellent last night, he sent me a message this morning that it really worked! He didn't get a single mosquito bite last night! I am so glad that my research paid off!
Did not open as it is a gift. Seller shipped fast and item came well packed.
I have been using the mosquito repellent mats daily as it is effective to prevent mosquitoes and flies from flying into the house. This is my reorder of 3 boxes every two months. Thank you!
i have been using the mosquito mats for about 1.5 years and it has helped to keep the mosquitoes away especially during the period of high dengue fever incidents. It's safe and easy to use at home.
Small form factor and the power on button is design to prevent accidental on or off. Love it.
I have been using the mosquito mats daily for about 2 years in my home. It is effective and flexible as I can place it anywhere at home to prevent mosquito coming into the home, especially when Singapore is experiencing regular dengue fever outbreaks. Prevention is better than cure.
Handy tools to bring when outdoor . Really keeps mosquitoes and bugs away . Great !
Arrived in time when the stock is depleting fast...
Replacement purchase. Have been a life-saver for my mosquito-prone wifey and daughter.
It's a very effective repellent device. Non of us got bitten on the entire trail walk. However, the device only lasted for about 3.5 hrs real time use instead of its claimed 5 hrs duration even though it was charged to full the night before our walk.
Super handy. Just clip and go. Love it!

Awesome piece for the add on blinker holder.Secured firmly.
Used 4 times so far and had bites twice. Doesn’t seem to do anything for house flies. Can’t really tell when to replace the cartridge. Overall experience not that great. Not to forget it’s abit heavy
