Overview

Experience uniform extractions across all groups all the time... permanently. The VST Precision Insert Basket is the essential espresso filter for those in search of the ultimate cup.

The VST baskets deliver consistent extraction performance over a wide range of concentration with reduced sediment. It is designed to extract properly and expertly amongst most bottomless portafilters, including Rancillio, La Cimbali, La Marzocco, and Nuova Simonelli, Quick Mill, Izzo, Rocket, Giotto, Isomac, Vibieme, and more. Each insert basket is uniquely coded for manufacturing QC and product authenticity.

The VST baskets were specially created with holes that were fabricated using a new micro-machine and finishing process. Each and every hole on every single basket was measured for the minimum and maximum range limits on area and diameter to a precision of +/- 30 µm. They were also calculated for circularity, placement, square area and any blocked holes before being considered fit for sale and fitted for Baristas. The hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck.

The VST Insert Basket was specifically designed to stand the test of time. The wide outlet angle prevents the filters from clogging and the anti-wear design ensures uniform performance for life of product. The structural integrity has been improved, able to withstand deflection from pump cycling without any premature fatigue failures.

Each insert basket is marked with a very unique 2-D bar-code to ensure true authenticity and performance. The 2-D bar-code stores the factory measurements, the quality reports, and even image data.

Disclaimer

The 20 gram, 22 gram & 25 gram baskets are meant to be used in bottomless / naked portafilters. Please be aware that these may or may not fit in most single or double spouted portafilters due to the depth of the basket. 

It is common for these precision insert baskets to appear somewhat flawed or cracked on the inside which, as described by the manufacturer, is "a normal cosmetic artifact of the radial micro-machine processing"

What's the difference? Ridged vs. Ridgeless?

Quite simply put - one has a ridge and one does not. If your portafilter comes equipped with a spring clip inside of it, than the ridged basket will lock into place. Why is this important? If you don't have a knock box on your counter, and you're banging your pucks out into a garbage can, you may have to go fishing for the basket because it's likely to slip out with enough force. 

Some people believe the ridgeless basket will produce a better shot of espresso because there are no imperfections, or 'ridges' if you will, on the basket and therefore make it less likely to channel.

Size: 58mm

Made in the USA

Great book! Practical and for developers that already use AI!
Format: Paperback
I purchased "Agentic Coding" by Claude Code due to my desire for an alternative to generic "Prompt Template" type resources related to AI-based development. This book accomplishes just that. As opposed to merely viewing Claude Code as a "magic box", the author has explained how to utilize it in conjunction with other actual development processes. The authors' emphasis on "context engineering" (i.e., structuring data/information; managing knowledge in a project; guiding an AI agent to produce consistent results vs. producing random/unknown results) represents the strongest component of the book. It should be noted that the book appears to be intended primarily for experienced developers with prior experience in software development and/or familiarity with AI-based development tools. Should you be familiar with Git, the command-line interface, and/or modern development processes, you may find this resource very helpful. Conversely, I did appreciate the fact that there were no novice-oriented descriptions provided throughout the book. The aspect of the book that I found most valuable, however, is the extremely pragmatic nature of the material contained within. The examples illustrated through developing/maintaining CLAUDE.md files; utilizing Claude Code in combination with GitHub Workflows; employing MCP Servers; and creating multi-agent or sub-agent workflows all seemed to reflect a clear focus on "real world usage" rather than theoretical constructs. In addition, each chapter builds upon previous chapters in such a manner as to provide a logical progression through which the reader can easily understand and ultimately implement the concepts learned. I also appreciated that the author included guidance on responsible utilization of the tool(s), as well as maintaining control over what changes are made by the agent. While numerous books regarding AI focus solely on what AI tools can accomplish, this book addresses both how to utilize these tools effectively in a real codebase, as well as responsibility and safety considerations. In summary, this is not a book for individuals completely inexperienced in either programming or generative AI. However, if you are currently experimenting with tools such as Claude, Cursor, GitHub Actions, or MCP, this is likely one of the more useful and practical books available on the subject. Recommended for software engineers seeking to transition from simply "prompting an AI" into establishing a repeatable/professional workflow process surrounding agentic coding.

⭐⭐⭐⭐ (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.
