Ensure Unfailing Alarm Delivery with the AJAX VHF Bridge
Introducing the AJAX VHF Bridge, a crucial transponder that provides your Ajax security system with an additional, ultra-reliable channel to communicate with a monitoring station. Designed for ultimate resilience, this module allows you to use Ajax systems in locations with unstable or non-existent internet connections, such as nature reserves, mountainous regions, or remote properties. By transmitting alarms and system events over VHF radio waves across vast distances, the vhfBridge ensures your security is never compromised, serving as either a primary or a backup communication link.
Core Features & Benefits
- Internet-Free Alarm Transmission: Guarantees that alarms are sent to the central monitoring station via VHF radio waves, completely independent of an internet connection.
- Universal Compatibility: Seamlessly integrates with any third-party VHF transmitter that has relay inputs, offering you flexibility and choice.
- Proprietary Jeweller Radio Technology: Leverages Ajax's secure, two-way communication protocol. It features block encryption, protection against spoofing, and frequency hopping to prevent jamming, ensuring all data is secure.
- Extended Communication Range: Achieves a remarkable radio communication range of up to 1,800 meters (5,900 ft) in open space between the module and the Ajax hub or a range extender.
- Impressive Power Autonomy: In the event of a power outage, an optional 7 Ah backup battery (not included) can power both the vhfBridge and the connected VHF transmitter for up to 75 hours.
- Advanced Anti-Sabotage: The device is equipped with two tampers that provide instant notification of any attempt to open the casing or detach it from the surface.
- Effortless Configuration: All 8 transistor outputs are easily configured through the user-friendly Ajax mobile and desktop apps, allowing you to specify exactly which events trigger an alarm.

Immediate neck and back pain
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
Nice full pillows that holds its shape, BUT was NOT good head and neck support. I noticed an immediate difference. From non existent to growing neck pain in the first night’s use, through the week.

Soft and comfortable
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
These pillows are incredibly soft and comfortable. They provide great support while still feeling plush and cozy. I’ve been sleeping much better since I started using them.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation.
However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through.
That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone.
Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.
