Summary: It's always worth spending the most you can afford on optical equipment. You can find binoculars that are much cheaper than these, but their performance pales into insignificance if you try these and the cheaper ones at the same time. Go on, go for it!
Summary: These may look small and leave you feeling they'd not be up to much but.... Wow! They're truly amazing. Fantastic for bird-watching and quite a surprise for this when you normally think that approx "8 x 42s" are the bees knees. These are expensive but they are really worth it. Easy to carry around in a pocket if you don't want them round your neck and then very quick to "wheel-up" and focus. Brilliant little things these. Treat yourself!
Summary: From early use, the binoculars themselves seem excellent. However, I have pointed out to Leica that the supplied carrying case is rather more bulky than that supplied with similar Trinovid binocs which I bought some years ago. It is less convenient for putting into pocket or handbag. This is a little disappointing since, after optical performance, portability is a prime property of 10x25 and 8x20 binocs.
