you cant go wrong for a fiver, but the slightest bump on these and one or both of the lenses will fall out, can be repaired with a bit of craft glue.
i actually regret not getting a pair now
I bought one for that price a couple of weeks ago in the Sunderland store, last one on shelf or I would have posted here. I thought it was store specific then. I haven't tried them yet so cannot comment on quality - but for £5 .... Bargain.
Store specific I assume?
