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.

BETTER THAN A CUP HOLDER
I had a cup-holder mount and it was always falling apart. No matter how it was turned, to unfasten my phone I had to move the spring part of the holder in the same direction that removes the entire clip from the stem of the mount. Of course, I eventually lost the clip. What a bad idea. And, in a 4-Runner, on my cupholder, MAPS sometines got lost and I would have to hold my phone up to the windshield for a minute to get back MAPS back on track. Also not a good Idea. We're not supposed to be handeling a phone and driving so holding my phone up to the windshield is kinda like flagging down a cop. (The 4-Runner has hand-free phone service, as well as some kind of circuitious navigation but it's always lost.) . So, for about $9 on sale, I though I would try one of these LISEN mounts. It works great ! Really. Easy to attach securely but scratchlessly it to my center AC/heat vent and It is infantly moveable. Swing the arm 360 degrees, in and out, phone up or saideways, and tilt the phone to me or the Boss. If I get bored, I can relocate it anywhere along the center vents, or even over to my side vent if I have nothing better to do.. It is sturdy, quiet, easy to clamp in my S21, and release is simplye by pushing the button on the back. Sooo much better that my previous mount, for a third of the price. It might be the best $9 you ever spent. And still worthwhile,if you have to shell out the $18. (But I always try to avoid paying full price for anything). Enjoy !
