The light in the back had a charging plug that absolutely would not accept the charging cable. It didn’t look weird, but it was too small for the USB cable it came with to fit into the light and charge it. I returned the helmet.

This is super comfy and the adjustable knob makes it fit perfectly! The light in the rear is great for safety and the chin strap is superb! For the price, I will never buy another helmet when another is needed. It feels great and I’m impressed with how securely it fits and I have no fear that it will do its job if need be! Buy this, you won’t regret it!!

Prompt shipping, good packaging. Once I got the straps adjusted for my head and chin I never evenknew I was wearing it. The light at the back of the helmet is an added plus, anything to draw attention to the fact that there is someone on a bicycle sharing the road with you.

Excellent helmet,Great fit, excellent cushion, light and very comfy. The light is a great bonus. Also, the finishing of the helmet is very nice; I got the Schwinn before but the Grottico is so much nicer.

The helmet is comfortable to wear. Seems very sturdy. The instructions for charging the helmet light were not very clear. Took a while to figure out how to remove the light and not cause any damage. Basically you have to pry it off the helmet and the charging port is in the back of the light. After charging, you just pop it back into the helmet. Pretty easy once you figure it out

The helmet looks good and is comfortable, BUT that visor was really hard to get on it no matter which part I tried first. Ended up putting the center first then the sides. I was so afraid of breaking the pins off! Ended up running the visor under hot water and gently using needle nose pliers to get the pins in the holes! I bought a gray one from them last year and I don’t remember having that problem!
