The ultrasonic mosquito repellent bracelet from Lenovo turned out to be more convenient than sprays
There’s a special kind of summer torture: you’ve almost fallen asleep, the room is quiet, and suddenly you hear that familiar thin buzzing near your ear. You have no energy to turn on the light and hunt the mosquito, the fumigator has run out, and using spray before bed is the last thing you want. Recently, I came across an ultrasonic mosquito repellent sold under the Lenovo brand. The manufacturer promises that this compact device helps repel insects without smoke, odor, sticky sprays, or replaceable plates. In other words, it effectively protects against mosquito bites. It looks very convenient and can be worn right on your wrist, which should come in handy during walks.
Drawbacks of Common Mosquito Repellents
Fumigators, aerosols, and plates work simply enough on their own. But in everyday use, each of these methods has its own annoying quirks.
Mosquito spray has to be applied to the skin or clothing. It can smell, leave an unpleasant feeling, and requires reapplication. It’s especially inconvenient to use at home when you’ve already taken a shower and gone to bed.
A mosquito fumigator is tethered to an outlet. On top of that, you need to make sure there’s still liquid or a fresh plate inside. Usually, you find out the refill has run out at the exact moment the first mosquito appears in the room.
Mosquito coils produce smoke, so for a bedroom or small enclosed room, this isn’t exactly the most pleasant option.
Against all of this, an ultrasonic mosquito repellent looks very appealing: turn it on, put it on your wrist, and you never have to buy anything else.
Common mosquito repellents have too many drawbacks for daily use
How the Lenovo Ultrasonic Repellent Works
The device is a compact sound signal generator that is worn on the wrist and looks like a fitness bracelet. According to the seller, it produces high-frequency vibrations that are supposed to prevent mosquitoes from approaching a person.
The main difference from a fumigator is the absence of chemical consumables. You don’t need to insert plates, pour in liquid, or add aromatic substances. There’s also no smoke or noticeable odor during use.
This simplicity is the device’s main advantage. You can carry it with you at all times, so the mosquito repellent works both at home and during evening walks, when mosquitoes are especially active.
The Lenovo repellent weighs 17 g and lasts up to 48 hours on a single charge
How the Ultrasonic Repellent Is More Convenient Than Spray
The first advantage is that the device has no smell. This is especially important for people who find scented plates, aerosols, and other insect repellents unpleasant.
The second benefit is the absence of ongoing expenses. When you buy a fumigator, you have to regularly purchase liquid or plates. Here, no consumables are needed.
The third advantage is mobility. A regular fumigator only works near an outlet, while this repellent can be carried with you at all times. I tried wearing it on my right wrist, while my usual fitness bracelet stayed on my left.
The device emits sounds but no one can hear them except mosquitoes
How Well Does the Ultrasonic Repellent Work
Evaluating devices like this is always tricky. I could say that no one bit me during the night while wearing this device. But that wouldn’t necessarily mean the gadget created an impenetrable protective dome around my bed, right? Maybe there were simply few mosquitoes in the room.
So I decided to test the repellent for several days in a row under identical conditions. And, to be thorough, I opened the window before bed to make sure mosquitoes would definitely get into the room.
I used the device from July 17 to 21. While sleeping, the repellent was fastened on my right wrist. I didn’t feel it while sleeping because I was already used to wearing a fitness bracelet.
Over those several days, I noticed that not a single mosquito flew near my ear during the night. A couple of weeks earlier, when it was hot outside, they kept me awake and bit up my arms. This time, I didn’t notice any itching, even though I saw a couple of small mosquitoes on the wall before going to bed. So the device can be called functional. On top of that, positive comments from buyers add to the confidence.
Reviews of the Lenovo mosquito repellent
Can Ultrasound Actually Repel Mosquitoes
Here, we need to be honest. There is no convincing scientific evidence that consumer ultrasonic devices reliably protect people from mosquito bites. In studies, such devices typically haven’t shown a consistent effect, so you shouldn’t rely on them alone in areas with large numbers of insects.
This is especially important when traveling to regions where mosquitoes can carry dangerous infections. In such situations, an ultrasonic repellent should not replace mosquito nets, protective clothing, and proven skin treatments.
But the device still has a clear everyday use case. You can try it at home, at a country house, or on an evening walk — when you need the simplest possible protection without odor or consumables.
Who Is the Lenovo Ultrasonic Repellent For
This device may interest several categories of buyers:
- people who dislike the smell of fumigators and sprays;
- those who frequently vacation at a country house or in nature;
- buyers who don’t want to constantly purchase replacement plates;
- people who need a small device for the bedroom, workspace, or outdoors.
