Recent estimates put the losses at £100bn/year so far [0].
Long term, the estimate is a 15% hit to the economy.
And only 12% of people think that it went well. (For reference, that's about the same proportion as 'Americans who believe shape-shifting lizards control politics, or aren't sure' [1].)
In personal experience, my purchases of UK products have taken a massive drop.
And that's not even mentioning the losses to the environment or human rights.. So... Not what I would call a mixed bag. More like a deeply homogeneous bag.
