No-See-Ums are worse than mosquitos, in my opinion. I had tried numerous different insect repellants hoping they would be effective against No-See-Ums. Most of them did not work. Some worked very short term & only on me & not the people around me since it was usually a spray that I put on myself. BUT then I found Thermacell. All of their products to keep mosquitos and No-See-Ums away. Not only do they work but they do so for several hours before needing the mat or butane cartridge replaced. And it works for a large area without the need to spray anything on your body. These new Patio Shields work the same as the original Thermacells but the Patio Shields look nicer. I use it at home & when camping.

I Purchased a patio Thermacell after my Wife saw how long it worked at my neighbors house. I have had mine a year now and just bought a whole bunch of refills. This Year I bought my son with one, For the patio at his apartment. His future in-laws saw it and now they are ordering one. I use it not only on the patio but when I am washing or polishing my vehicles keeps the mosquitoes away.

We bought a few of these 6 months ago and love it just dont like the fact that none of the stores carry anything more than the refills that come with both the Mosquito repellent mats and fuel cartridges. We go through so many more fuel cartridges and they are out of stock online.

I bought this Patio Shield Repeller last summer and I couldn’t believe how good it worked. I can’t be outside without having it on (about 15 minutes before I need it) because mosquitoes love me! When I get bitten it makes a huge swollen welt so without my Thermacell I can’t be outside at all.

I bought this package a few weeks ago with a lantern one as well and the 120 hour refill pack This item works but not for the period stated on the box If there is a lawyer out there I hope we can have a class action lawsuit going for this pricey product that tho it works for maybe an Hour and a half certainly doesn’t work for four hours like it says the mat should They need to create a product that does what I say and quit doing false advertising

I feel like I've tried everything with no success. Then I read a review on Thermacell and decided to give it a try: best decision ever! In Alberta, Canada our mosquitoes are relentless (day or night). It takes less than 5 min from turning on the Thermacell and you can actually see the mosquitoes come in, hover and leave! In the very worst of mosquitoes I've needed to use 2 of these thermacells for complete protection! As you'd expect, if its windy the Thermacell isn't as effective. I highly recommend this product!!

I bought this 2 weeks ago and have used it every night since. Before I purchased this my wife and I could not sit on our deck in the evening without being over run with mosquitos. Now we sit all evening mosquito free. As I said in the title it's the very best. Thank you.

My friend urged me to get this product after I complained about how much Off I was buying. I was skeptical but eventually bought the patio shield. I have been extremely surprised with this unit. I place it under the table and kiss ankle biting mosquito's goodbye! Awesome!

Used first time last ight - our dinner was virtually mosquito free! The longer we dined the more we noticed no biting or buzzing! I bought two units and we dine on the deck regularly - even before Covid- and we will test them again soon - I'M CONFIDENT THEY'LL DO THEIR JOB!

Disclosure: Thermacell sent this product to me in return for an honest review. I paid for shipping. Otherwise, I received what looked to be a retail boxed product. The short: Overall, the new Patio Shield had a lot of thought put into the industrial design. Unfortunately, the mosquito repellency did not work for me here in Austin, Texas. Ultimately, that's what matters for a mosquito repeller. The long: I own the MR150 portable repeller from Thermacell. I've tried using it during hunting, camping, and on the patio, but similar to the Patio Shield, I still had mosquitos literally fly over and past the heated allethrin pad and bite me. There's definitely possibility Central Texas mosquitos have developed an immunity to allethrin; I don't know. I know many people who swear by Thermacell, so it obviously has to work to some capacity, but it hasn't worked well for me. Ultimately, this is the reason for the low score I'm giving this product. Disregarding the effectiveness of the mosquito repellency, the physical product is well designed. The top cover (lid): One of the best features is the removable top cover. The problem with the blue allethrin pads are that they dry out when sitting out. The Patio Shield's cover helps to alleviate this. But the cover is not fully sealed, so the pad will still eventually dry out. When the Patio Shield is in use, you can lay this cover upside down and seat the Patio Shield upright inside the concave space. An etching around the Patio Shield's base will help to indicate when it has seated level inside the lid, but it does not securely clip in and so can still be easily knocked over. Repeller pad storage: Another great feature is a storage space beneath and inside the Patio Shield where you can store additional unopened alletrhin pads. There are four pairs of narrow plastic protrusions where a single unopened pad can be wedged in and held out of sight. The space is small, so if you'd need some smaller dextrous fingers to get them in there. Would be easier if the butane cartridge is not installed, but having all four pad holders filled may make screwing in the butane cartridge difficult. Butane ignition check portal: The clear window to check whether the butane is lit or not is located at the top edge of the Patio Shield's cylinder shape and is large enough to make checking for the pad heater being lit is easy. Butane flow and ignition switch: This is my least favorite part of the design. While the rotary switch at the bottom of the Patio Shield is aesthetically nice, it has the same smooth slippery plastic as the rest of the product. Even with the two finger divots molded into the rotary switch, gripping and twisting this switch can be tricky if using the design queues to only use your thumb and forefinger. You'll have better luck by laying the base of the Patio Shield fully into your palm and place as much of your hand's surface area and grip onto the rotary switch. If you have weak hand strength or suffer from arthritis, igniting the butane on the Patio Shield could prove difficult. Thermacell could add some grippy grooves or stippling in their next revision of the product to help with this. In summary, it's a well designed product. I just wish it repelled mosquitos here in Central Texas.
