CRC Cheap MX Helmets – Any Good ?

Hi,
I am after a budget Full face helmet.
I won't be using it daily, but would like one when I go to 'play' in the freeride area of GT for example.
After looking around for quite a while, I can't help but be tempted by these

The only FF helmet I've tried on that fitted well was a Giro Remedy. But for up to half the price, are the O'Neal and Animal ones worth a shot?

Any advice ?

Heavy but ok. Bell Bellistic is a decent option at £30?

When I tried on on, i found the Bell chin guard doesn't come low enough. Literally my chin and jawbone were below the guard. ( Kinda defeats the point I felt !) 🙂
