Russ,
Mine has been really well used. I did "pimp" it with black stove enamel to match my cup. Its now chipped. To match my mug
It is bloody brilliant - far better than that bit of BCB plastic tat. In fact, when you want to make some more, I'll take 3 please. I think my pics of it in use are well known - I have also sussed out that it works well with a billy hanger attached to the mug (I can do piccs if you wish)
My review
The "Capped Crusader" fits over the cup and is easy to remove after a boil to add coffee, milk etc to your cup. The "D ring on the lid means it can be "hooked" off after prolonged cooking (SAKs have a special tool - Rus's lid id the only real use I have found for it). Post cooking / boiling, the lid is cool enough to pack before the brew is cool enough to drink.
The BCB piece of plastic tat is hard to fit, sticks into the cup meaning you get scalded removing it to add your brew mix. It also has a bloody great hole for the steam to escape increasing brew time.
BCB - absolute crap - costs £2 and not worth it.
Russ's "Capped Crusader". Can't think how to improve it 5*
Red (I really do want 3 more)
