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.

So happy to have this for the outdoors while sitting watching the children play with. I love that it sprays a great distance with no batteries or outlets needed. Love that it has a variety of color choices and good battery life its chemicals safe and content away from the children and its compact nice looking desigm

A friend told me about the Thermacell when I told her I can hardly go outside in my garden anymore. I am such a mosquito magnet! I was skeptical but ordered it because I'm willing to try anything. As soon as it arrived, I set it up out on the patio and went back inside for 10-15 minutes to allow it time to create my "dome of protection". I was able to sit out on my patio for 2 hours and came in completely unbitten. It was amazing! I've used it several times since with the same result. My sister just ordered one today after I told her about my experience. She can't wait for it to arrive!

I saw the patio shield advertised on sale a few months ago. I had never seen the product before, so I did some research. Despite the praising reviews, I was skeptical. Mosquitoes love me. Whenever I am outside during the summer, I inevitably get swarmed and end up with several bites that itch for days. But despite my skepticism, I decided to try the product since it was on sale. Using it for the first few times, I thought maybe we weren't having as many mosquitoes this season since we weren't getting "bugged". But then we took it to a party across from a park. Not a single mosquito bothered us the entire humid evening (until the propane ran out...oops!), then we noticed the mosquitoes immediately. I have yet to receive a bite while using this product. It definitely works and I have recommended it to anyone who will listen.

Purchased this item to help with the HUGE mosquito problem in our back yard. We back up to a wildlife area with a pond and marsh which is beautiful but a nursery for mosquitoes. This rendered our deck off limits as dusk began, that is until we tried Patio Shield. We were able to relax "bite free" for a little over 4 hours last night. We are telling the neighbors to get one of these!!!

I just had my patio poured and was looking forward to sitting out there enjoying it, however the mosquito's were running me back into the house. I researched and found Thermacell Repellents and bought one, the first time I used it, no bites, I couldn't believe it. I bought another one.

This device is a lifesaver especially inside our RV & campsite area!

We have not used it often enough yet to really know how we like it or how well it works.

Works well for small areas

Does the job, mosquitoes stayed away. I wish the range was a bit wider but overall a good product.
