Uncompromised, Multi-Layered Entry Protection
Secure your property with the AJAX DoorProtect Plus, a next-generation wireless detector that offers three layers of security for any door or window. This device instantly detects opening, vibration, and changes in tilt, providing immediate notification of the first signs of an intrusion. It protects your home even when windows are left open for ventilation, thanks to its advanced accelerometer that registers changes in vertical slope, bangs, and any vibration, sending an instant alarm to the hub. Ready to operate straight out of the box, the battery is pre-installed for an effortless setup that takes just minutes.
Core Features of the DoorProtect Plus:
- Triple-Sensor Detection: Combines a high-end magnetic opening contact (reed switch) with a sensitive shock and tilt sensor (accelerometer) to guard against various intrusion methods.
- Advanced Accelerometer: Registers vibrations, impacts, and changes in vertical slope angle greater than 5°, making it ideal for protecting windows left open for ventilation.
- Jeweller® Wireless Technology: Ensures secure, long-range communication with the Ajax hub up to 1,200 meters in open space. The encrypted, two-way communication prevents jamming and device forgery.
- Exceptional Battery Life: Operates for up to 5 years on the pre-installed CR123A battery, minimizing maintenance and ensuring long-term reliability.
- External Detector Input: Features an external contact for connecting third-party wired detectors, allowing you to easily expand your security system's coverage.
- Effortless Installation: No need to disassemble the detector. It connects to the hub with a single click in the Ajax mobile app and mounts in minutes using the included SmartBracket.

Great toys for aggressive chewers
Size: Medium/Large, Color: Turkey Day Drumstick - Large
These are great toys they last a while they are destroyed after a while but both dogs are aggressive chewers but they last about a year and a half. And they are go to toys they have one that is a shark mouth and they love it I have bought 4. (two of them the pups lost ).

Durable and Fun, Just Gets a Bit Rough
Size: Medium/Large, Color: Chopper - Large
This is a really good toy overall, especially if you have dogs that love to chew. My dogs were immediately into it—they play with it nonstop, toss it around, and stay entertained for a while, which I love. It definitely holds up better than most toys we’ve tried.
The only reason I’m giving it 4 stars instead of 5 is because over time it does start to fray a bit and gets a little rough, especially with heavy chewing. It’s not completely indestructible, but it still lasts longer than a lot of other toys.
Overall, still a great buy and I would recommend it if your dogs need something tough but fun!

Worthwhile!
Size: Medium/Large, Color: Turkey Day Drumstick - Large
I have a small dog with a really strong bite! Usually have to buy toys that are meant for bigger dogs. This has lasted us for what feels like forever. It does sound very heavy when dropped! My dog loves it though! Would definitely recommend!

Instant fav for my girl but looks like I'll be replacing often 🤪 she is a super chewer. She loves the soft vs hard combo on toys. Damage in the pic is within 10 mins. 😬😬😬 excellent quality

Foreign body risk for dinosaur dogs
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
My dog Bert had foreign body surgery 10 days ago because he swallowed a piece of a toy, so I was looking for something stronger, like for a tyrannosaurus rex. This toy had good reviews, so I bought it for him.
In 25 minutes and he'd chomped a chunk of the blue water part off. Bought the toy around 8am, gave it to him around 8pm, and it was in the trash by 8:30pm.
This toy is definitely NOT for super chewer tyrannosaurus rex dogs like Bert. But definitely IS a toy that is pretty sturdy and strong for dogs who don't have the bite force of a dinosaur.
