Not very effective for my needs
[This review was collected as part of a promotion.] Stem Zone Mosquito Repellent Device is an easy to use and durable system. The ultra compatible USB-c charging port makes it easy to recharge. The include citronella essential oil pod was not difficult to install and is typical in its fragrance. There is an indicator light so you know when the device is on or needs to be charged. With all of that, I did not find that I experienced the protection I was expecting or maybe it only works exclusively on mosquitoes and not any other biting insects.

Easy to use, smells better than traditional repellents, and actually helps keep mosquitoes away.
[This review was collected as part of a promotion.] Living in Florida, mosquitoes are a constant problem, so i was really curious to try this STEM Zone Mosquito Repellent device - and honestly, it works better than I expected. The setup was super simple right out of the box. I like that it's rechargeable with USB-C and doesn't require messy sprays or strong chemical smells. Instead, it uses essential oils like geraniol, citronella oil, and lemongrass oil, which give off a light, fresh herbal scent that's much more pleasant than traditional bug repellents. I've been using it on my patio and near my workspace during the evenings, and I definitely noticed fewer mosquitoes around the area. The device itself feels modern, compact, and quiet, and l appreciate that it's designed to be safe around people and pets when used as directed. The green indicator lights also make it easy to know when it's running. Overall, this is a really convenient and cleaner alternative for creating a more comfortable mosquito-free zone without constantly spraying yourself with repellent.

Low profile, does the job perfectly
[This review was collected as part of a promotion.] I use this extensively when I am in my backyard. The device does not make any noise. The manual was straight forward. The smell is pleasant and not overpowering. I like that it’s rechargeable. Not sure how long the wick lasts. Make sure you open the lid the first time to take the wick out of its cap and insert it into the lid.

Less bites than usual
[This review was collected as part of a promotion.] I was skeptical at first because I couldn’t smell anything, so I wasn’t sure if it was working. But I sat outside in my backyard and didn’t get nearly as many mosquito bites as I normally do. And mosquitoes love me. I live in what feels like mosquito city, so that says a lot so far. I do think it’s helping.

This thing actually worked!
[This review was collected as part of a promotion.] We used it in the backyard while BBQ for the weekend. When we originally went out, we getting bitten by mosquitoes. I remembered we had this to try and ran to pull it out. It was nice that it came with some charge because I could use it right out of the box. It was super easy to set up. Just open and screw in the refill. It smelled like citronella. We went back out and was able to grill without the bother of mosquitoes. This thing actually worked. I stood in the grass with no issue.

Strong repellent smell
[This review was collected as part of a promotion.] Very strong smell of repellent. I like this because I don’t need to worry about spraying myself with bug spray which I hate. This one just needs to be charged. We used it in our recent outdoor camping. It says 8 ft of coverage but I doubt that, as I was feeling some mosquito 🦟 touch my legs. But again I haven’t been bite yet. And my husband felt it works.

Love it
[This review was collected as part of a promotion.] Works great. I live in Florida so it can get buggy and this definitely reduces the feeling of getting bit once I turn it on. I like that nothing has to go on your skin and can cover a group of people.

Worked for one week.
Worked for one week. I left it in the sun to recharge almost all day and won’t even stay on, plenty of oil left in diffuser.

So far, so good!!
[This review was collected as part of a promotion.] So far, I'm loving this device. I can smell the citronella, and I haven't seen any mosquitos! I plan to keep using it once the weather really warms up, but the device itself seems well built, quiet, and effective.

Compact, take it anywhere
[This review was collected as part of a promotion.] Love the compact size, can take this baby anywhere. Living in South Florida, and living on a LAKE, the mosquitos are insane. It worked pretty well during the day, haven’t tested at night when they are even peskier.

Good for small areas
[This review was collected as part of a promotion.] This has been a great addition when gardening in Texas. These mosquitos are relentless but the STEM zone mosquito repellent did help ward them away! My only wish is that the area covered was a bit larger. I found myself moving it around basically to be near me. Step is easy and the recharging capacity makes it easy to use in different scenarios.

Great portability and perfect for small spaces.
[This review was collected as part of a promotion.] We are using this solar powered mosquito repellant system to help with our front porch area. It is able to be recharged daily and allows us to sit outside without being bit. Perfect for a 8x10 ft space. It is also super portable and we could move it to the backyard if we needed to.

Works from a good distance
[This review was collected as part of a promotion.] So far I like this mosquito repellent. It’s quick and easy to install the refills and it covers most of my small backyard as far as keeping the mosquitoes away. The product worked almost instantly, and you can move it around if needed. I haven’t tested it out for any weatherproof qualities yet.

Effective and expensive
[This review was collected as part of a promotion.] Super easy to use. I love that it can be solar-charged or usb-charged. I find that the solar charging is most useful on the everyday basis. It is a relatively small device where the capsule is popped into the middle and the essential oils/scents are released from the top of the device. It smells like citronella mostly, which is probably the most common ingredient for repelling mosquitos. I like that it’s portable, so you can bring it with you in the car, camping, put it outside where your furniture is, under the gazebo, near the pool, or on the kayak. That being said, it also only has a range of 15 feet of protection, so unless you keep the device pretty close by in one area for a long period of time, it won’t be as effective. I will say that with there only being 1 capsule that lasts up to 18 hrs, this is pretty expensive. If you spend all day outside with this, like 6-12 hrs, you’d only get 1.5-3 days use out of one capsule and have to replace pretty frequently if you’re a frequent outdoors person. We’ve used a different device before, same concept as this one, but it was bulkier/heavier so I would prefer this one but the price tag is definitely something to consider for future buyers.

Easy to install
[This review was collected as part of a promotion.] Easy to install and use. I love that it’s so easy to transport to different places on my porch. I haven’t used it much in order to tell if it really keeps the bugs away but I can update my review when I know for sure!

Keeps bugs away mostly
[This review was collected as part of a promotion.] I like using this while I'm working outside in the garden. It does a pretty decent job keeping mosquitos away. The power lasts a pretty long time but that may change over time. Easy to put together

Mosquito
[This review was collected as part of a promotion.] This is a good product to have outdoors as it can be solar charged. It's similar in weight to a bluetooth speaker. As far as getting rid of mosquitoes sometimes it's a hit or miss but it's better than nothing.

Amazing mosquito repellent device!
[This review was collected as part of a promotion.] This Stem Zone Mosquito Repellent Device is really cool and useful! It uses essential oils to repel mosquitoes up to 15 feet. The design is nice, sleek and compact. So far I have used it on my front porch but I believe this will be amazing on a camping trip! I love that it can be charged with a charging cord but it is also solar powered! It has 2 lights under the power button to indicate the power and also when you need an oil replacement! The setup is quick and easy but you do have to be careful not to touch the wick or get the oils on your skin or in your eyes. I would say it is definitely effective in minimizing the mosquitoes, I’m excited to test it out in the summertime when a lot more bugs come out!

easy to use!
[This review was collected as part of a promotion.] I put this on around 30 minutes before hosting a bbq outside and it worked pretty well! Still saw a few mosquitos but not nearly as many as i would without! it’s super quiet, easy to use and set up! Overall will continue to use this when outside on my patio!
