anyone got a Nitro N312 Retro limited edition?????

Hi eevvereebodee
Just bought this helmet for looks (very cool), price (very cheap), fit (very comfy for a very big scone (bonce for those south of the border!))combo and wondered if anyone else has or had this helmet to see what they think and how it served them.
You may have seen it in shops, matt black with two white stripes running fore to aft.
I never even really looked at nitro before as they seemed cheap and nasty but this ticked all the boxes but I am concerned about longevity.
