ToughTested Mammoth Windshield Phone Mount with Double-Ribbed Gooseneck, Extra-Large 4.25” Suction Cup, 4-Way Locking Claw Grip, 360° Rotation & One-Button Release

I brought this after checking many holders. This one works perfect when we fix to the glass. Quality is very good for the money. Before I brought few but those were not effective. I like the air suction for glass and it is strong even for heavy phones.

This is the best phone mount I have ever seen. Its in my husbands truck as he drives thousands of miles for his job. He said he hits potholes bumps etc and this held his phone tight regardless of the road conditions. He said that this is the best toughest phone mount available & he wants me to thank Home Tester Club for choosing us as we really needed something to hold the cellphone while driving for gps etc.

I have this on the windscreen of my concrete truck. There are insane bumps and movements and this mount doesn't budge. Very good quality. I do wonder how long the suction plastic will last, considering it faces the sun all day

I got this for my work truck. I often have to drive off road on some fairly rough terrain and this thing holds solid! I was surprised how big the suction cup is. No sticky residue on the suction cup like some others. As long as your window is good and clean when you put it on, the suction will definitely hold everything in place, I am surprised how well this has done for me. Probably going to buy another just to keep on hand in case this one goes missing.

So far so good with this very large phone holder. In the past I have had issues with phone holders attaching to my windshield but this 1 seem to attach with ease. This holder has the ability to hold all phone sizes especially the large 1's with the bulky cases which I really appreciated about it. Easy to follow directions and within minutes I had it installed and I was ready to go. This is excellent for road trips or daily driving, you have the ability to install it anywhere on you windshield and it even can survive sudden hard stops which I unfortunately tested out a few times. All in all, I like this phone holder and I would certainly recommend it to everyone.

Its a decent value, if you just want something to mount on windshield. Mine died after a short while. The teeth broke. And yes, brand new the phone would shake a lot. But it never fell off, suction was strong in my vnl truck. Just wanted to try the walmart stuff. If i could add another important thing. While mounted. I wasnt able to use camera since its blocked off by the plastic. Not that you would want to touch the mount while driving but there are mounts that dont block your camera and are sturdier than this one.

Purchased my 1st mammoth mount and it lasted 2 years at a professional driving job. Installing and removing it at least twice a day sometimes more. The teeth broke off on the adjustment arm. Got a new one, it didn't even last 6 months. The teeth on the cog under the suction cup basically disintegrated. The next 2 have had the same issue. PLEASE UPGRADE THE MATERIAL USED IN THAT PIECE. Better plastic or metal. Great product when it doesn't self destruct.

The design of it is wonderful, but the quality is lacking. I had mine for roughly 2 months, and where the arm meets the suction cup snapped and isn't repairable. If they'd spend as much time on the quality as they do the design, it would be worth it.

Overall, this product seems durable and made with quality materials, but I find a major design flaw in the way that the phone holder part connects to the base. Every time I adjust my phone, the phone holder part disconnects from the base. It's like the lock mechanism doesn't actually keep it locked in place. So my phone just kept coming off and I found it really frustrating. It wouldn't be a problem if for some reason you put your phone on the phone holder part and then never moved it ever again. But who does that?
