Instant Security, Zero False Alarms

Introducing the AJAX DoubleButton, a wireless hold-up device meticulously engineered for situations where a real threat requires an immediate response. Designed to prevent accidental activation, the DoubleButton ensures that help is summoned only when you truly need it. Its innovative design requires a simultaneous press of two rigid buttons, separated by a plastic barrier, making false alarms from carrying it in a pocket or bag a thing of the past. This device is your reliable link to safety, providing peace of mind in both residential and commercial properties.

Guaranteed Alarm Delivery with Jeweller Technology

At the core of the DoubleButton is AJAX's proprietary Jeweller radio technology, ensuring secure and reliable two-way communication with the hub up to 1,300 meters away in open space. This advanced protocol protects all transmitted data with block encryption and a dynamic key, preventing device forgery and sabotage. In case of signal jamming, the system intelligently switches frequencies and notifies you and the security company. A clear LED light indication on the device provides visual confirmation that your alarm has been successfully delivered.

More Than Just a Panic Button

The DoubleButton's functionality extends beyond emergency alerts. While its primary role is to signal for help in case of intrusion, fire, or medical emergencies, it can also trigger sophisticated automation scenarios. With a single confirmed press, you can activate specific or all sirens on the premises, trigger a smoke machine, lower roller shutters, or lock electric doors, adding a powerful layer of active response to your security system.

Built for Reliability and Longevity

Engineered for durability, the DoubleButton's body is resistant to dust, splashes (IP55 rated), and extreme temperatures ranging from -10°C to +40°C. It operates for up to 5 years on its pre-installed CR2032 battery, eliminating the need for frequent maintenance and ensuring it's ready when you need it most. Whether carried as a keyfob or mounted on a surface with the optional Holder accessory, the DoubleButton offers versatile and dependable protection.

⭐⭐⭐⭐ (so far)
Format: Paperback
I'm maybe a third of the way through this and already rethinking how I talk to coding agents. The reframe from "prompt engineering" to "context engineering" sounds like semantics until Marco walks you through why context poisoning, context clash, the Goldilocks zone for system prompts. That chapter alone reorganized something in my head. I keep going back to the line about garbage in, garbage out being the real reason agentic systems underperform. The hands-on stuff lands well too. Building the HookHub project from scratch, wiring up Playwright MCP, watching Claude generate a CLAUDE.md file and then not automatically loading a memory file you just created — that moment where you expect magic and get silence instead? That's the kind of honest teaching I appreciate. It made the "why" behind memory hierarchies click.

Essential Reading for Developers Serious About Agentic AI Workflows with Claude Code
Format: Paperback
Agentic Coding with Claude Code is easily one of the most practical and forward-thinking AI development books I’ve read. Instead of treating Claude Code like a simple chatbot, this book shows how to turn it into a true agentic development platform capable of handling real-world engineering workflows. What I appreciated most was how actionable the content is. The explanations around slash commands, hooks, persistent memory files, and MCP servers are incredibly clear and immediately useful. The author does an excellent job balancing foundational concepts with hands-on implementation, making advanced topics like multi-agent orchestration and hierarchical delegation approachable for experienced developers. The chapters on MCP and context engineering were especially valuable. Most AI books stay at the surface level, but this one dives deep into structured context sharing, workflow automation, and scalable AI-assisted development practices that actually matter in production environments. I also liked that the book focuses heavily on maintainability and control. It doesn’t just show flashy demos—it teaches how to safely integrate AI agents into existing terminal and IDE workflows while enforcing coding standards and keeping projects organized. The examples using Claude Code with Next.js projects were practical and helped connect the concepts to real software engineering scenarios. The sections on subagents, planning workflows, and reusable automation patterns opened my eyes to entirely new ways of approaching AI pair programming and development productivity. If you are a developer, AI engineer, or technical lead looking to move beyond basic prompt engineering and build reliable, scalable AI-assisted workflows, this book is absolutely worth reading. Highly recommended for anyone serious about modern agentic coding and AI-powered software development.

Agentic Coding - all the right pieces in the right places
Format: Paperback
Before obtaining a copy of this book, I had not yet become familiar with Claude Code and didn't realize how robust AI Pair Programming is now. However, I did know and have rigorously promoted the absolute importance of Context (via Context Engineering) in any AI-prompted tasks, including coding. This book brings all of that together in an incredibly useful book (dare I say... a comprehensive toolkit and handbook) for AI-prompted coding in these multiple modalities: IDE, command-line, and pair programming. It covers memory management, agents, subagents, multiple-agent systems, context-sharing, orchestration, enforcement of coding standards, code maintenance, and more - for executing AI-assisted development with confidence. I highly recommend this book. Disclosure: the publisher provided me with a free review copy of the book.

Perfect size for me
Color: Light Color Series, Style: Waffle Pattern, Color: Light Color Series, Style: Waffle Pattern
Washed the cloths before use with just detergent. Pretty much stayed it shape and fluffy texture. It lathers well with any soap and drys fast. Love the texture size more than the exfoliating size. Texture side is great for sensitive face cleaning. The exfoliating side did soften after repeated use. I feel it is still little to rough for the face, but great for the body.

Great quality
Color: Light Color Series, Style: Waffle Pattern
These are a bit oversized compared to regular washcloths but that makes it easier when exfoliating your own back. The one side is soft and plush. They are easy to wring out. They wash up nicely. I use a linen bag when washing them but it's not necessary.
