Thats correct.
And i tried on some crowbars and liked the fit, as for the splices, i wasnt a huge fan. One of the major selling features for me with the i/o is that they come with another lens and theyre easily interchangeable. Ive never had multiple lens options and i kind of like the idea of it instead of using my night lenses always.
I can get the crowbars for on average $40 cheaper than i/o's but the the crowbars never come with an extra lens and the i/o's usually do. Not to mention that if i am going to find some crowbars with two lenses or just buy a back up lens my self, i dont want to be fighting with the goggle to get the lens in.
Im a bargain hunter and dont have much money at the moment so price is definetly a factor for me, im just trying to decide that in the long run is the extra money worth it for the i/o's.
Im getting new gog's with the intention of not buying new ones for a while.
