I have had quite a few pairs of bins over the years for birdwatching and visited a well known retailer in Norfolk last week. The above bins (do not confuse with the Frontier) retailed at £299 and IMO were the equal of the Leica/Zeiss at more than twice the price! Possibly made in China, but superb optics nevertheless. The 8x36 were also good but the x43 had the edge.
Reasonably light also. Try them.
