Unrivaled Protection with Precision Glass Break Detection
Secure your property with the AJAX GlassProtect Jeweller, a sophisticated wireless indoor detector that provides immediate notification of a break-in through any window. This sleek black sensor is engineered with advanced technology to distinguish the unique sound of shattering glass from everyday noises, ensuring you are only alerted when a real threat occurs. Its miniature design seamlessly blends into any interior while offering powerful, reliable security.
Key Features:
- DualTone False Alarm Prevention: Utilizes a highly sensitive electret microphone and a two-factor authentication algorithm. The detector must register both a low-frequency impact sound and a high-frequency shattering sound to trigger an alarm, effectively ignoring false triggers like thunder, barking dogs, or traffic noise.
- Wide-Area Coverage: A single miniature detector can secure an entire room, recognizing glass breaking from up to 9 meters away with a 180° detection angle.
- Jeweller® Wireless Technology: Guarantees a stable and encrypted two-way communication with the Ajax Hub at a distance of up to 1,200 meters in open space. The system is protected against jamming and device forgery for ultimate reliability.
- Exceptional Battery Life: Operates for up to 7 years on the pre-installed CR123A battery, minimizing maintenance and ensuring long-term, uninterrupted protection.
- Effortless Installation: Ready to work straight out of the box. Simply connect it to your Ajax security system with a single click in the mobile app and mount it in minutes using the included SmartBracket.

Soft, Warm, lightweight, Cozy
Color: Cream, Size: Full/Queen
When I first received this blanket I washed it by itself in cold water with detergent. I did not use a fabric softener or a fabric sheet. I air dried it completely and then put it in my dryer on air fluff for 10 minutes. No shedding and it came out just like I received it. I was concerned about shedding with some of the reviews but I had no issues with that whatsoever. It's warm yet lightweight. I didn't want anything that would make me overly hot because I'm always hot anyway. It takes that cool edge off when you still want your overhead fan on. My daughter said she likes it better than the one she has. I can't remember the brand. I feel it has a good quality. Just make note to wash it as instructed and it'll hold up well and look just as nice as the way you bought it. I'm not sure how the other reviewers that didn't leave 5 stars washed there's, but it couldn't have been the correct way.

Soft, warm, sometimes shed
Color: Shadow Grey, Size: Full/Queen
LOVE these blankets! The only downside is some of them shed. They will keep you so warm and they are very soft.

Great size and warm but didn't feel as luxurious and soft or thick as I thought
Color: Shadow Grey, Size: Twin/Twin XL
This blanket is not quite at fluffy or thick as I would have wanted. It feels thin but soft. It does keep me warm though and it's the perfect size to have multiple people cuddle on the couch while watching a movie?
