Having moved on to a Tassimo after three years of a Dolce Gusto, I've been working my way through the (much larger) selection of Tassimo drinks. This latte - along with the non-caramel version - is currently my favourite.
The "real" milk here seems to taste better than the powdered stuff in the Dolce Gusto, and the foam lasts longer too. I'm not normally a big coffee fan - I hardly drink it during the day - but I always look forward to a mug of this when I get home from work, or as a mid-afternoon treat at the weekend. I find the "automatic" dose is just right; I don't add more water to stretch it. Not being used to "flavoured" coffees, I did think the caramel taste was a little too artificial at first, but now I've tried a few from Costa I actually prefer this one.
Just be careful of the price - make sure you're buying from Amazon, otherwise you'll end up paying TWICE the price for the same item! In this case, Amazon actually work out over £2 cheaper than Tesco, so worth a look (plus I've noticed supermarkets are often out of stock of this variety - it seems quite popular).
