My husband really likes his Dolphin Helmet. We only had one problem when applying it to the wall. It is definitely a 2 person application. The issue we ran into was in the facemask area, the bottom strap ripped when taking it off of the backing material. Warning: this area is very weak and thin. Be extra careful when taking it off of the backing paper. We were extremely careful and slow and it still tore. After reworking and applying I got it to lay so you really can't see the tear.
Other than that, it looks really nice. Now to apply the other helmet. 🤞I would have given 5 stars if the material was a bit thicker and didn't tear.
