I spent entirely too much time quadruple checking around to make sure these were going to fit my specific car (2022 Chevy Traverse). Apparently the newer headrest options for specific car makes and models are more narrow than others? Who knew?! We not only live pretty much 30 minutes away from all the things, but we also frequently go on weekend trips and the occasional annual long haul vacation away with the kids in tow, so keeping the children occupied when looking out the window or talking isn't ideal is a must. Among the countless reviews of several products along these lines, including the OEM options, many begroaned instability with large/heavy devices. Well... I bought 2 of these and tested it on a 3 hour drive one way, and both held my children's 10.2in Gen 8 Ipads (Inside Osmo cases.... essentially a thin casemate case) and not once did we have falls or swinging around of the Ipads! Granted, you do need to fully tighten down all of the adjustment knobs to prevent that from happening, INCLUDING the ball joint! Logistically, I felt getting all of it set up into the correct position prior to the drive and locking everything in vs. leaving some room for my kids to move the devices around would be better for our specific needs, and I was correct on that. As long as the kiddos could see and reach the screens to change selections, they left it well enough alone.My only negative on the sturdiness side is 1) The further it is extended out, the more "jiggling" from the car is noted. The device is still secure in the holder, and the holder is still secure on the headrest... they aren't going anywhere... but if you have a child sensitive to motion sickness, be aware that the jiggling of the screen in front of their eyes will be more pronounced the further out the device is from the headrest. It's easily fixable by pushing it closer to the headrest where less momentum is placed on the extended arm, but as a parent of an easily motion-sick child, I just wanted to make others aware of that. 2) I can see the possibility that the adjustment knobs may loosen over time or eventually break. It's all plastic (with some foam pieces glued in for better grip hold where it needs to be), and depending on the weight and size you are putting on the end of that long arm and how far you extend it out, tighten and retighten the knobs, etc.... its a high possibility that this product is not going to last a lifetime. I could be entirely wrong, but that's my personal observation. I wouldn't hold it against the product itself... I wouldn't expect this sort of product to last ages, but I know some can be pretty critical in their search so again... I thought it worth mentioning.All in all, It's money well spent imho. It's not an eyesore, it's functional, does what it says it does, and its versatile. We plan to test out the Switch in it next to see how it does, but I can already say, these don't extend far enough out to be able to share one small screen between 2 captains chairs... it comes relatively close, but I imagine it'll cause a battle in children's eyes on who can't see as well.
