I've been using GDM for all my helmets *by M***Z on Reviewed in the United States on August 15, 2017* These helmets are awesome! I've been using GDM for all my helmets. My last one the GDM Duke -140 saved my life 2 weeks ago. I went 50MPH into a telephone pole face first. Because of the Duke I walked away with only a concussion and a dislocated shoulder. Great product and a great team that gets these out to me. Couldn't be more happier !! ### ⭐ Don't waste your money on this *by C***N on Reviewed in the United States on December 27, 2017* The helmet sucks, I've had mine for a few weeks and then little red button on the strap fell off, when I tried changing the face shield...the locks broke off (I've changed a million of these, never seen anything like that) no breathe deflector, it whistles, I don't think the vents are functional, and I used a tape and measured my head correctly but it was still tight. Very tight. The only redeeming Factor is the helmet doesn't give lift off at high speeds and it looks cool. I got to go down today to replace it and this is the only after having it a few weeks ### ⭐⭐⭐⭐⭐ Great customer service *by R***3 on Reviewed in the United States on January 9, 2018* This helmet is a fantastic quality. The original one I ordered was slightly small and customer service worked with me to get me into the correct size. I'll be a return customer for sure! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/73653613-gdm-duke-helmets-dk-346-full-face-motorcycle-helmet-matte](https://www.desertcart.hr/products/73653613-gdm-duke-helmets-dk-346-full-face-motorcycle-helmet-matte) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
