Review: Offers safety; easy to fit & comfortable to wear - This is a good helmet! It's comfortable & easy to use, fit, & adjust. I love that it has a light for being seen. It's a nice color & a reasonable price. Finally, I feel that it offers a good level of safety & I'm going to dispose of our old helmets. It is lightweight & has ventilation. This new helmet is SO much nicer than the old helmets!
Review: Great Safety Helmet!!! - Well, I purchased my first ever electric scooter (at 74) that has a seat and rear basket from desertcart and in the product manual it states to use safety gear. Well, I only travel 1/2 mile round trips to work so I ignored that warning; the result was I took a hard fall and bruised my ribs; banged my knee; scraped my elbow and yes, banged my head on the sidewalk. That was a hard lesson learned !!! So this was one of the safety items I purchased. The helmet is solid! It’s a one size fits all so I’m not sure what to say about that. I do know that out of the box it fits me perfectly; a little tight but I prefer it that way. I really like the added safety light in the back of the helmet. Lights really well for when I leave work at midnight. Not sure how to change the battery, when needed, but I’ll worry about that when the time comes. I guess my only gripe is that rain visor on the front of the helmet; it comes off easily but that is actually my fault because I store it in my old backpack that is secured to the rear basket which is probably a little bit too tight for my helmet. But, at work I have to store it or everyone will play with the helmet and light. This is definitely a 5-star product!!! Well constructed; great added safety feature with the rear helmet light; solid straps; comfortable!

### ⭐⭐⭐⭐⭐ Great Safety Helmet!!!
*by T***D on August 8, 2024*

Well, I purchased my first ever electric scooter (at 74) that has a seat and rear basket from Amazon and in the product manual it states to use safety gear. Well, I only travel 1/2 mile round trips to work so I ignored that warning; the result was I took a hard fall and bruised my ribs; banged my knee; scraped my elbow and yes, banged my head on the sidewalk.

### ⭐⭐⭐⭐⭐ Easy to use, light weight, ventilated
*by M***S on August 7, 2025*

This helmet fits comfortably. It has so many vents, so it doesn’t get too hot. I like the visor. I really like the light in the back! It’s very light weight. I like that it’s a matte coating and not shiny. You can turn a knob and fit this helmet better to your head or loosen it. It’s worth the money if you ask me. My son was wearing my helmet and fell off his scooter. He banged the helmet up a bit but he was safe and his head and face were protected. I bought him this same helmet in black now. I definitely recommend this.
