I've just got some of the Home Bargains / B&M ones.
They feel slightly lighter and say they burn "Over Two Hours" as opposed to "Up to Three Hours".
I'll have to have a burn comparison at some stage, I'm up in Scotland for a few days soon so I might be able to do it then.
Good price though.
B&M do them? Brilliant, I've a pal lives near a B&M store in Linlithgow will give him a shout.
Would love to try these.
