All You Need to Know, and Nothing You Don't, to Write JavaScript for the Web and Beyond JavaScript plays a key role in modern software development, not only because it is the only language that runs inside virtually all web browsers, but also because it has become widely used for back-end and general-purpose development as well. Although JavaScript is a big language, you don't need to learn "everything" about it to get started, just how to use it efficiently to solve real problems. In Learn Enough JavaScript to Be Dangerous, renowned instructor Michael Hartl teaches the specific concepts, skills, and approaches you need to be professionally productive. Even if you've never programmed before, Hartl helps you quickly build technical sophistication and master the lore you need to succeed. Treating JavaScript as a general-purpose language right from the start, Hartl offers examples for creating dynamic effects in browsers and for writing scripts and modules using Node.js. Focused exercises help you internalize what matters, without wasting time on details pros don't care about. Soon, it'll be like you were born knowing this stuff--and you'll be suddenly, seriously dangerous. Learn enough about . . .

Excellent Product and Exceptional Quality and Service – Highly Recommend!
I recently purchased the LISEN Car Phone Holder Mount [Military Stable] and couldn’t be more impressed! From the moment I unboxed it, I could tell it was built to last. The design is sleek and modern, and it holds my iPhone 15 Pro Max securely without any wobbling, even during bumpy rides. The military-grade stability lives up to its promise—this mount stays firmly in place, and the adjustable clamps fit my phone perfectly. What really stood out to me was the ease of installation. It attaches to my car vent effortlessly, with no tools required, and doesn’t block any air flow, which is a huge plus. It’s also compatible with various phone models, including the latest iPhone 16, so I know it will be a long-term solution for my future upgrades. In addition to the great product, the customer service from Linsen was outstanding. They provided timely and clear communication, answering all my questions before I made the purchase. It’s rare to experience such excellent support these days, and it made my buying experience even better. If you’re looking for a reliable, sturdy, and easy-to-use car phone holder, this is the one to get! https://www.amazon.com/dp/B0CXLQDY5B Highly recommend!

Well made, but not a good fit for Volvo XC40
One issue with this style of holder, is that the swing arm and holder add a fair amount of weight and extends that weight away from the vent, applying quite a bit more leverage on the vent. It may not be as much of an issue on horizontal vents, but the vertical vents on an XC40 will want to swing side-to-side with all that weight. As for the build of this particular holder, my only real gripe is the adjustment for the swing arm - after tightening the knob, there will still be some play in the arm...you have to jiggle it while tightening it down to fully secure it. The position of the release button allows one-handed removal of the phone, but really only works by pinching with your thumb on the screen. The clip for the vent accommodates relatively wide fins and the tabs can be rotated to help with stability or removed to provide more clearance (though rubberized tabs would be much more helpful).

Good solid product
Purchased in February of 2025. Very solid item. Use it constantly in our 2011 4Runner and 2017 CX5. This unit attaches firmly to vent fins in both cars. I use iPhone for maps programs and streaming music. When traveling I'm constantly rotating device 90 degrees to use phone in portrait and landscape positions. Unit has shown no signs of losing ability to firmly hold desired position despite frequent rotations. It holds firmly where you place it. Initially I had concerns about placement on dash and blocking view of radio face, clock, MPG indicator, and other displays. Didn't take too long to realize the flexibility of this thing and the many, many positions you can place it due to multiple rotational joints. Pricing was fair. If this ever wears out, I will want to buy another.

Happy with purchase, easy to install, exactly what I needed
For many years, I'd been using a similar item with a wedge-type vent mount that finally stretched out and became unusable. When searching for a replacement, I wanted to try one with a different type of mount and I looked at many brands/types of holders. This one seemed to be the best item for the price ($8.99 at the time). So far, I'm very happy with it. I got it in a timely manner, and it was exactly as advertised. I had no problems attaching the hook to the vent fin and securing it. I use it for a GPS, and since the holder is designed to stand out away from the vent a bit, my device is easier to see than previously and details are easier to read. It wobbles, occasionally, but the holder's not loose, at all, and it doesn't affect my ability to read the device. The frame is barely just big enough to hold my GPS, but so far that hasn't been a problem. The device slides into the frame easily, locks securely, and stays put. The holder pops open at the touch of a button on the back, and the device can be removed easily, without issue.

Prevents me from adjusting the air vent up or down
It's true that it doesn't block the air flow. I had to put it on the left passenger side vent to retain the ability to point the driver's air vents where I want. With it over there, I have to turn my head too far to the right when I'm driving to see my phone, and the passenger can't adjust the vent up or down. Also, phone can't tilt as far left and right as other ones. Good price, unique design, easy to install, feels sturdy, holds iPhone SE fine, and doesn't block my view of the entertainment system.
