MULTI-CHANNEL COMMUNICATION & PRIVATE CONVERSATIONS
The 50S delivers not one, but three different intercom modes available to Sena riders: Multi-Channel Open Mesh Intercom™, Group Mesh Intercom™, and Bluetooth Intercom.
Multi-Channel Open Mesh Intercom (Open Mesh) features the industry’s first Mesh Intercom™ channel system. Similar to standard handheld or CB radios, the 50S allows users to switch between nine different channels when operating in Open Mesh mode. Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom™ network. It also supports a near-limitless number of users within a range of up to 5 miles / 8 km (min. 6 riders @ 1 mi / 1.6 km intervals). With this ease of connecting, huge user capacity, incredible range, AND the inclusion of the nine-channel feature, the 50S Open Mesh Intercom mode is sure to be a game-changer for large group/club rides.
If you prefer a private group conversation, simply switch to Group Mesh Intercom mode. Group Mesh supports a single, private group for up to 24 participants and the same amazing range as Open Mesh. To ensure privacy, only invited users can join the Group Mesh chat. Whichever of the two Mesh Intercom™ modes you choose, you’ll enjoy the robust reliability engineered into Sena’s Mesh network.
Traditional four-way Bluetooth Intercom mode continues to be an option for connecting other Sena Bluetooth-enabled users within a 1.2-mile range. Additionally, 50S users can pair with a Sena Bluetooth Intercom user and ‘bridge’ them into a Mesh Intercom™ conversation.

TAKE CONTROL WITH VOICE COMMANDS
There’s no need to lift a finger when you can ask the 50S to handle it. Voice commands give you control of Sena’s 50S system functions, such as answering the phone or starting up a Group Mesh session. The 50S supports these system voice commands across eight languages, including English, French, German, Spanish, Italian, Chinese, Japanese, and Russian!
But what if you’re running low on gas? “Hey Google, please give me directions to the nearest gas station.” The 50S can connect to Google Assistant and Apple’s Siri with just a simple voice command allowing you to tap into the power of your smartphone’s features, including GPS navigation, music playback, voice dialing, or a myriad of other options. Wondering where the nearest BBQ joint is? Need to find a hotel for the night? Want to listen to your favorite band? Whatever it is, all you need to do is ask: “Hey Siri” or “Hey Google”! THIS is how to #RIDECONNECTED

Excellent resource for Christian parents raising the next generation!
Format: Paperback
I am currently researching and reading materials for a book I’m writing regarding how to build a strong foundation in children before the age of 10. I’ve read quite a few books so far, and I have to say one of my favorites is Grace Based Discipline. The author has done an excellent job, and and her witty humor makes this an enjoyable read! Because of this book, I am ordering the other books that her and her father have written!

Finally, a practical parenting book!
Format: Kindle
Prior to reading this book, I didn’t feel confident in my approach to discipline. I would read parenting advice from different sources and sway back and forth from one extreme to the other—overly strict to too lenient. The approach of grace based disciple is balanced. The author recognizes that children will act like children and we shouldn’t expect them all to act like little robots. However, they still need discipline (not punishment!) for their misbehavior. She gave very practical lists of what consequences work best at each age and for each personality type, and went beyond that to say how to truly address the deeper issues associated with the misbehavior.
If you are wondering about her view on spanking (because most authors take a very strong stance on this) I think this book is very beneficial no matter which camp you are in. In the appendix, the author addresses spanking in a nonjudgmental way. She gives cautions if you decide to use spanking, and gives cautions if you decide not to use it.
My only criticism of this book is that one chapter talks about how we need to recognize the “home country” (personality) of each member of our household and she suggests using an assessment to determine what “country” your child is from. However, you must pay separately for the assessment and it isn’t cheap. This idea of what “country” you and your children are from is referenced again and again in the book so I feel like it should have been included in the appendix. However, this book is still worth it. Don’t let that keep you from buying it.

Mixed feelings
Format: Paperback
I had the opportunity to finish this book in one day of reading, while my 3 kids spent the day with grandparents. It is a very easy read, very accessible. Karis' style is very informal and she employs a lot of humor (and hyperbole), and that may be refreshing for some, though I found it distracting. I hope my criticisms will not be taken too harshly, and am certainly glad that others have found it inspiring or enlightening! We desperately need more grace based parenting in our homes and churches as we strive to undo the influence and damage of the punitive methods that have marred the face of Christian culture for so long! We need more books like this, that can reach every believing parent where they are, and inspire them to parent with the same grace and wisdom our Heavenly Father employs!
All that said, this was my experience reading the book: I felt the numerous anecdotes take up valuable space and time that would be better spent digging into passages of the Word and working through practical application. I was disappointed to not find a whole lot of either. If you are well-read on child development and "alternative" methods of discipline and childrearing (from those considered to be in the "anti-spanking camp"), you will find nothing new here. I didn't care for the rebranding of the classic four temperments and promoting supplemental Family Matters products... You can easily find many free tools and information reguarding personality psychology on the internet, and you will have a much deeper understanding. But personality is a shifty thing in youth anyway, and if you are not inclined to pursue that kind of study, I promise that simply resolving to spend more unstructured time with your children, to slow down and observe them at work or play, to listen with full attention, considering their perspective before answering or judging, you will learn more than what could ever be summerized in a personality type. Pegging a child in any brand of personality typing has it's own drawbacks. It can promote unfair assumptions, lead to misunderstandings, and cause confusion when trying to understand more subtle or complex behaviors and attitudes.
I appreciate her reasoning for not digging into the spanking issue in the main content of the book, setting that aside in the appendix in the back. She does a good job highlighting what gracious spanking looks like if you choose to do so. I am of a similar opinion that it is not a crucial point of doctrine and isn't always an issue of abuse or neglect either. It truly is a parent's prerogative and responisibility to consider the Word and the research and their own consience on the matter. If you do spank, follow her guidelines and you will not go wrong! I did find her characterizations of non-spankers, like myself, a bit condescending ("lazy", "fearful"), but to be fair she is addressing the extreme. If only you knew how much effort and time in research and reflection many of us sacrifice to employ better methods! It is very proactive approach and it is difficult work! I think she could have done a better job to include an objective summery of arguments in both camps for better understanding, but I really appreciate her exhorting those in both camps to avoid contention and judgement. It should never be an issue that causes us to break fellowship with a brother or sister!
There is a good chapter on what she calls the "3 P's", a helpful framework for discerning the whole truth of God's word. But as far as parenting goes, personally, I didn't find anything new or particularly helpful here. I will be gifting this to a good friend/newer mom who will likely get more out of it than I did. Maybe you will too!

Excellent, succinct, intro to Marxism...
Format: Paperback
Richard Wolff’s Understanding Marxism is an excellent and highly accessible populist work that introduces Marx’s critique of the inherent contradictions and inevitable problems that plague – and will continue to plague – capitalism. So, he sets out to show how the contemporary experience and understanding of the relationship between employer-employee emerge from because it is the modern manifestation of the historical distinction, which is hierarchical, oppressive and ultimately “exploitative, between master-slave and Lord-serf - Zizek, in his small text The Relevance of the Communist Manifesto, offers a unique response to this line of critique and reasoning.
Above I mention the accessibility of the writing – in fact, there is a crystalline clarity to it - and if you have watched Wolff’s show or listened to his interviews, it’s as if Wolff is speaking in his usual manner that avoids academic jargon and communicates his ideas directly. This is an extremely helpful and useful guide to understanding Marx, and I am hoping many young intelligent politically-minded university students will read it – e.g., those who might be unfamiliar with Marx - because it offers a sensible corrective to the ill-informed Marxist critics on the so-called “intellectual dark web” (IDW) who repeatedly, without properly understanding Marx, scapegoat him and employ him as a bogeyman to enhance the arousal of fear and alarm with their rhetoric.
Ultimately, and here I agree with Wolff, Marx might be said – bound intimately with Marx’s notion of “species being” (a term Wolff avoids) – to show why “ending exploitation [is] necessary to actualize social commitments to liberty, equality, brotherhood, and democracy” (36-37). So, instead of a utopian (end-of-history) communist or socialist model for society, Wolff, through his reading of Marx, offers what might be termed a philosophical or even commonsensical (and achievable!) model of what a more socially aware and humanly grounded workplace might look like – one that is Marxist in nature and instantiates people coming together in more “democratic, egalitarian ways.” (71).
Wolff also directs readers to primary source material for further study - so, all the quotations included are traced to Marx's original writings, which readers are encouraged to seek out.
To conclude, readers must be aware that this pamphlet – indeed, this is what Wolff calls it – does not attempt to serve as a broad or sprawling introduction to Marx and his writings. Thus, when ordering it, be aware that it is not akin to academic introductions and critiques of Marx such as Peter Singer’s Marx: a Very Short Introduction (OUP) or Allen Wood’s Karl Marx (Routledge).

Excellent Essay

Wolff is a one of the best people I know of to deliver a quick handbook to Marx. He delivers a master class on this complicated subject and I have long respected his views on economics and politics.
