Instant Peace of Mind: Remotely Control Your Water Supply

Introducing the AJAX WaterStop, a smart, wireless water shutoff valve designed to provide ultimate protection against water damage. This essential smart home device combines a high-quality brass valve with a powerful electric actuator, allowing you to shut off your water supply in just 5 seconds from anywhere in the world using the AJAX app. Whether you're at home or away, the WaterStop offers immediate control and monitoring, ensuring your property is safe from leaks and floods.

Automated Protection & Smart Scenarios

The WaterStop seamlessly integrates into the AJAX security ecosystem. It can automatically shut off the water when a LeaksProtect sensor or a third-party detector is triggered. Create intelligent automation scenarios through the app: shut off the water when you arm your security system, set a schedule for water flow, or prevent the valve from seizing with a weekly automated cycle. These customizable scenarios provide an unparalleled level of automated protection, tailored to your lifestyle.

Robust Engineering for Maximum Reliability

Engineered for durability, the WaterStop features a powerful electric actuator with up to 8.5 N·m of torque, capable of closing even a stuck valve without risk of damage. The device is compatible with both hot and cold water pipes and can operate for up to 3 years on its pre-installed batteries. For added flexibility, it can also be connected to an external 9-12 V⎓ power supply. Its proprietary Jeweller wireless technology ensures a secure, encrypted, and long-range connection to your AJAX hub up to 1,100 meters away in open space.

Simple Installation & Manual Override

The AJAX WaterStop is designed for straightforward installation without the need for complex tools or disassembling the enclosure. The electric actuator can be mounted in four possible positions, making it adaptable to tight spaces. In case of emergency or power loss, a manual lever and a control button on the actuator housing provide immediate, tool-free water shutoff.

Great speaker wire
Size: 14AWG-50FT
I ordered this speaker wire to replace my speakers in my car. I highly appreciated that there are 50' included on this spool, it's perfect for rewiring the stereo speakers in a car (or house). The wire appears to be made well and is the correct gauge. The sound quality is great with my new speakers, and I am highly impressed. I recommend this speaker wire to others, it's exactly what I needed and has met my expectations for high quality speaker wire.

Higher resistance than expected
Size: 14AWG-50FT, Size: 14AWG-50FT
I like Nilight products, I really do, but this one isn’t as good as it could be. After reading other reviews I wanted to take a different test approach and measure the resistance of the whole roll. I thought this might explain the low rating of 5.6A at 12V. I believe my test explains this rating. First, you need to make sure you understand that this is copper clad aluminum. It is clear in the ad title but make sure you are good with that. The test consisted of me removing the entire 50 feet of wire from the spool to reach the other end. I then stripped back the end and tied the two together securely. Only soldering would have produced a more complete contact. I then tested the resistance of the roll with an Agilent U251B multimeter which gave the reading in the pic of .75ohms. That’s not much but compared to what I found on several charts that was high. The average resistance of 14 gauge 41 strand copper wire should be 2.63ohms per 1000 feet or .1315 per 50 feet. The wire tested 5.7 times greater resistance. Obviously aluminum will test with more resistance than pure copper but I was unable to find what those values should be. The insulation is thick and durable so abrasion wear shouldn’t be an issue if routed properly. The wire may still be great for your application but if you are considering pushing this wire to the load limit you may want to upsize to 12 gauge.

Best lights you can get for the best pricing!
Color: 5in Round LED Pod, Color: 5in Round LED Pod
I have had man different off road lights over the years for many different vehicles. Let me tell you about these 5” aux beams. I ordered these lights to go on my 2500 as ditch lights and I am beyond impressed! The lights showed up well packaged. When opening the box, the instructions where right on top and by far one if the easiest sets of instructions I’ve had for wiring diagrams. The lights were packaged and wrapped in foam all the way around to protect them from shipping. The wrapping of the lenses for scratch prevention was perfect. The included wiring harness was packed in a bag and laid out very easily for installation. The harness hooked to the battery and then to the lights with easy quick connects and had more than enough length to put the lights anywhere. Once they were mounted and installed I hooked them up to my aux beams switch panel with ease. Now for the lights! The brightness is beyond bright enough to see miles away! These lights will shine anything you could ever want to see. The spot flood combo work exceptionally well for all situations and darkness. The side shooter stretch them beam out to the sites and can see all the way across. The running lights tie in very easy with your turn signals for extra turn lights or running lights. Heavy duty is an understatement for the quality of these lights. I’m still running them after several months with no water intrusion and still as bright as the day I installed them. The price for what you get, is far beyond better than other top brands! I will be buying more of these for my next off roading set up!

Too big for a tiger, but works well on the fiddy
Color: 4*2.5in Cube LED Pod
Not as bright as the graph says they are, or maybe I'm not in a dark enough area at night. But they definitely are blinding. Were too big for my adv bike unfortunately, but they work good on my truck as ditch lights. Not too bulky looking like the cubes are and no wind noise that I can hear. Definitely lights up the wma trails and the side shooters are very helpful. I will note though that as soon as your hood gets dusty it becomes blinding from the inside side shooters though. so I painted the yellow lens cover on the inside sides and it helps a lot with the hood glare.
