They are in Germany though. Might be a bit of a hassle with Brexit now.
But I guess straps like the outer shell one have to be ordered from the US so maybe that doesn't matter.
Yes, I heard good things about them too. I have the standard "mini buckle" version though. I rarely take the strap off and they never come loose so that's all good for me.
Gonna throw in another option. This is the one I am using and it works quite well. It also has a magnetic fidlock buckle on the stabilizing strap.
