Nearly Perfect…

I purchased this mount for my 2016 Acura RDX. I mounted my phone on the windshield near the A-pillar, as close to the dash as possible.

The suction cup is solid and the suction twist mechanism is a game changer.

However, the combination of the windshield and dash angles make it a challenge to mount the phone with the charger attached without it being so high as to significantly block visibility.

I wish the mount arm was an inch longer so I could mount the phone lower.

Awesome product

I bought this so I can set my Galaxy 25 in it and run my JBV1 app with my Valentine 1 radar detector and Waze at the same time while on road trips or my commute to and from work! This is the best window mounting system I have ever seen! Highly recommend!!

Perfect mount

When there was no other option to mount a phone holder other than drilling holes in my dash, I found this when looking at Bulletpoint website. I like this and it's holding to the windshield. It has a rubber suction cup which I think won't melt to the windshield like my last one did. Super

The most awesome mount

I purchased this mount to use in a rental van on a trip to Montana. We were on National forest roads and if you have never been they are not the smoothest. I had my magnetic mount and everything stayed perfectly intact. I am very impressed.

Window mount

It’s a great option for the rav4. There isn’t too many options for a mount unless you want to block the vents

Just broke today. The one screw that holds the mounting plate pulled out of the threaded hole

Fantastic

The product is well-made and versatile. I can quickly move the phone holder between cars without much effort. The craftsmanship and quality are excellent. I was disappointed that the holder was made in China. I try to be American whenever I can.

Suction Cup Mount 3.4" Diameter with 20mm Connector End

The suction cup mount works very well. It will stick to my window/windshield and it's not coming off. The suction cup mount will not mount to my dash i have seen some pictures where they have it mounted to the dash. My dash has a texture to it and it just won't stick. Over all it works like it's supposed it.

Most awesomest mount

I bought this mount to mainly to go in my work truck. Also so I could move it vehicle to vehicle. So far it has work flawlessly. The cup is large enough to hold a big phone. I’m even wondering if it would hold a tablet. Great job bulletpoint on the design.

Product FAQs

We have a page dedicating to helping you choose the best phone holder depending on your usage and your phone size: Phone Holder Help

Our DiabloM6 magnetic phone mount requires a thin metal plate affixed to the back of your phone.

Please note that this also prevents Wireless Charging.

The DiabloM6 is not directly compatible with MagSafe equipped iPhones.

The metal plate features adhesive on the back and must be attached to your phone or case. It may not stick to all phone cases. For example, many silicone cases have non-stick properties that may not work with the metal plate.

If you have a MagSafe-compatible phone and you do not want to apply the metal plate or you wish to maintain wireless charging functionality, we offer a MagSafe-compatible phone holder.
