Ergonomics were a priority: it sits comfortably in the hand for confident control during extended jobs. The optimized weight distribution supports balanced, low-fatigue polishing—ideal for mobile detailing or daily shop use.
A standout highlight is the 800× switching speed (high-frequency control), which enables exceptionally precise modulation of polishing movement. This lets you dial in the tool perfectly for different paint systems and task requirements. It’s complemented by a powerful 21 V, 5 Ah fast-charge technology that gets you back to work in no time.
The A4500 Pro isn’t just about specs—it’s built tough for continuous professional use under demanding conditions. At the same time, it runs quietly with low vibration, noticeably improving working comfort.

A bit repetitive
Format: Paperback
The Family Systems approach makes a great deal of sense and is very helpful. But this book seems to be somewhat formulaic - every case looks the same.

Extremely enlightening!
Format: Paperback
A psychologist recommended I read this book as my daughter and I were having issues. Wow! What you'll find in this book will change your whole thinking about relationships with family members. Very enlightening as to why we all behave as we do and what affect our behavior has on the development of our children. A MUST read for every parent. I bought a copy for each of our children and grandchildren to read.

Some good advice
Format: Paperback
Roberta Gilbert's "Extraordinary Relationships" offers useful advice for dealing with family relationships couched amidst an examination of systems theory. Although it is more technical than a lot of self help, it can be used by a general audience.
Gilbert examines the theory of Murray Bowen, who countered notions of individual psychology (like those of Freud) with the theory that personality develops as a result of a family unit. The nuclear family, like a herd of amimals, reacts against each other, speaking a common language that is known only to them. Children raised in that family then detach from the family to form their own adult relationships, where dynamics may follow the family system.
In order to heal adult problems, the author offers some practical advice, like taking the time to observe old patterns as they crop up (family Christmas fights come to mind) with the dispassionate mind of an observer. The author states that individuals will better be able to understand family dynamics and their role in them by doing this.
I've read this book twice, and it has helped me better understand my family, and my role within it. I would recommend it for those who are seeking to better understand their family of origin, and what they can do to improve their present life through understanding the past.
