Ultimate Water Leak Protection for Your Smart Home

Introducing the AJAX WaterStop, a smart, remotely controlled water shutoff valve designed to integrate seamlessly into your AJAX security system. This device provides peace of mind by automatically shutting off the water supply in as little as 5-7 seconds upon detecting a leak, preventing costly water damage. The WaterStop combines a high-quality Bonomi Industries valve with a powerful electric actuator, all controllable from anywhere in the world via the Ajax app. You can also set up automation scenarios to shut off the water at specific times or when you arm your security system.

Robust Design and Reliable Performance

The AJAX WaterStop is built to last, featuring a durable brass valve that is compatible with both hot and cold water pipes. Its powerful electric actuator delivers up to 8.5 N·m of torque, ensuring it can shut off the valve even if it's stuck. The device operates on pre-installed batteries with a life of up to 3 years, and also has the option for an external power supply. For manual control, there is a button on the actuator and a lever on the valve itself.

Advanced Wireless Technology

Utilizing AJAX's proprietary Jeweller radio communication technology, the WaterStop ensures secure and reliable two-way communication with the AJAX hub at a range of up to 1,100 meters in open space. This advanced protocol uses block encryption and frequency hopping to prevent sabotage, spoofing, and data theft, providing a robust and tamper-proof connection.

So small
Size: 10.5, Color: Allblack015
They seemed comfy enough, but the sizes are very small compared to my typical shoe size. Buy at least a whole size up if youre going to get these

ULTRA LIGHTWEIGHT EVERYDAY SNEAKER
Size: 12, Color: Grey015, Size: 12, Color: Grey015
You should know that if you're specific on your footwear like I am, these may be the shoes for you. All too often shoe companies make shoes that look stupid by trying to do too much. These shoes are great because the most important appearance in a shoe is what they look like on feet from your POV. The toe box is spacious and the lace front is normal, not too wide like Adidas Ultraboost. The only downside is these shoes wear out quickly. They last about 1 year with daily use before the outsole starts to to go. All in all price for value, 5/5.

Sizes run smaller, at least for me
Size: 9, Color: Allblack015
I have a 8.5/9.0 size shoe, depending on the manufacturer. I purchased these exclusively for work, on a slippery (paper dust) concrete floor and a forklift. The main con here is there is NO size 9.0, only 8.5 or 9.5. I think this is odd, but I am sure there is some reason for it. Nonetheless, I ordered the 9.5 in black. I was expecting it to be a little large. However, this shoe fits me perfectly. Thus my reasoning that, for me, these run small. These stretch. They are not constrictive. I despise tight constricting shoes since they usually hurt my feet. I also hate shoes that are too big as they tend to make me trip (I am already uncoordinated). They have a softer rubber/plastic'y sole. I dont know the material, other than "Phylon". I have only worn for two weeks and they are comfortable. I do feel their flexibility. These shoes are not a stiff shoe. For me, that is a plus. However, non slip they are not. In defense, I have not experienced any shoe that is non slip on the floor at my work. The smooth concrete floor is often covered in a finite paper dust. This makes it slippery and no shoe can stand up to my lack of coordination. My biggest like is they are very breathable. My feet sweat! During the hot days, I need my feet to breathe. These do that quite well. Also, I enjoy and actual solid sole. Some other "fancy" shoes I purchased were comfortable, but they had a very thin tread and wore out quickly. They did not last long. Time will tell if these last long. Another plus for these shoes, is there is very little text on the shoe. The only text is on the tongue of the shoe. They are also easy to put on, almost like a slip on shoe that does not fall off. Out of the box (and still now) there are no defects. It appears to be well put together. If I can get 8 months use out of these, I will be absolutely buying again.

$30 descent shoe with Foam sole no arch support
Size: 13, Color: Lightgrey015
I got these and they were in plastic smashed together to conserve space. I cut the plastic wrapper and put them on. They are a minimalist shoe. Not much support. It's like they tried to copy the sketchers, but took out 25% of the quality. It's a good soft foam sole, light weight and slip on. I wore these for nearly 9 hours on concrete at my job with out foot pain. For under $30 shoe you probably won't be able to build a sole that is arch supportive and made for longevity. If your going out for a few hours around the town, these will be comfortable. I am ditching the inserts and putting in real inserts to see if these will work for multiple purchases. Great styling no issues with build quality that I can see. Again these are under $30 not $75, so if your expectation is a durable shoe good support these are not for you. On the other hand they're comfortable for going out shopping and eating out while looking descent. I wouldn't wear these for more then a few hours as they're not really proper fit shoes with arch supports.
