Alpinestars - Supertech SM-10 Dyno Helmet
With years of development, Alpinestars has raised the bar in the high-end motocross helmet market with the all new Supertech SM-10 motocross helmet. Featuring carbon fiber construction and innovative features that are exclusive to Alpinestars such as the A-head interior liner for supurb fit, four different EPS densities and a MIPS rotational layer that offers a high level of impact absorption. MIPS is a proven safety system that helps reduce the rotational movement in the helmet by absorbing and redirecting the energy/forces that would otherwise transmitted to the brain.
The SM-10 helmet is filled with new technology such as Alpinestars patented Visor system that has been developed to provide the right level of resistance to release when needed from impacts in any direction. The interior of the SM-10 helmet has been designed with maximum ventilation in mind. An interior air network channels incoming air through the helmet to keep rider's head cool, while continuing to pull hot air away and through the large exhaust vents.
The helmet has been designed for riders that wear neck braces and those that don't The bottom area of the helmet is raised to clear rider's collarbone area as much as possible. This gives dirt bike riders confidence while riding on the track, trail, or anywhere else. The SM-10 is also hydration system ready, as it has a channel inside the chin bar specifically for hydration tubes.
BTO Sports is your Alpinestars SM-10 Helmet source with all the colors and sizes you need.
Features:
- A-Head: Patented system allows easy adjustment of the angle that the helmet sits on your head. MIPS system is also included in the helmet.
- Visor: Patented system has been developed to provide the right level of resistance to release when needed with impacts from any direction. The visor system is light weight.
- Collarbone: The bottom side of the helmet is raised to clear the collarbone as much as possible for riders who choose not to wear a neck brace system. In addition, the bottom trim is soft on the collarbone area.
- Mouthpiece: To maintain strength of the mouthpiece, a radial ridge has been incorporated which assures complete strength to the front of the helmet.
- Maximum Ventilation: The Interior air network channeling has extremely high ventilation values made possible by the airflow design and the location of all air intakes and outlets
- Four Individual Shell Sizes: XS/S, M, L, XL/2XL

Not a reliable charger
Color: BLACK
The car holder portion of this item is incredible. It automatically closes around your phone when it detects it and keeps it very snug. You press a button on the side to release and that's it. Now the charging part of this is pretty bad. i understand that wireless chargers are not as fast as wired but when i use this it would take over 3 times as long as a wired charger. If a plug says 45 min to charge this would take at least 2 and a half hours. It is great for roadtrips or if you drive constantly but for any short trips the charging is negligable. I also have used it without a case to see if that was the issue and it was not. At the very least it keeps your phone at the same charge on short trips so I guess that's good.

Great product, great for the delivery drivers out there
Color: BLUE
If you are debating about getting this dash mount, get it. I haven't fully tested the wireless charging but I have a pretty uneven surface and it sticks extremely well, the holders that hold the phone are electronic and they sense whether or not the phone is in there once open so it won't just close randomly. If you turn the car off, you can release it, go away for a few minutes and then come back, set the phone on there, and turn the car back on, and after a few seconds it will clamp. If you press the button while the car is off it will clamp as well. I would recommend testing whether or not it wireless charges on whatever one you get, just in case of a defect, and you don't even need to take the film off to test it. This one is one hundred percent worth the money..

Recommend
Color: Black
This a great little phone mount. It works for my iPhone 17 pro max. I drive a lot of dirt roads where I live in the mountains, and the magnet holds up to plenty of bumps without dropping my phone. Easy to install.
Pros:
-very simple installation
-strong magnet
-arm rotates for adjustment
-ball and socket joint allows tilting with a good amount of resistance to hold its position (when fully tightened)
Cons:
- for model 3 users, anything other than next to the steering wheel can block a portion of your windshield viewing area
-could have more modularity if offered with more arm attachments
Conclusion:
RECOMMENDED. Very stable and functional mount with a minimalistic design that still allows for some adjustability.
If magnet weakens over time, or the sun damages the plastic to the point of breaking from brittleness then I will post updates. I will also update for any modifications I make for more adjustability.

This economical solution works perfectly
Color: Black
Very happy with this car mount. The magnet is plenty strong to securely hold my iPhone in its magnetic loop case. It’s plastic but it’s sturdy and fits on my Model 3’s screen perfectly. It has an adjustable height that I can mount my phone with full clearance of my steering wheel.
Don’t waste your money on a metal mount, this inexpensive mount serves the need perfectly.
