For the price of the Leica you are buying a great pair of binoculars with a very good laser rangefinder built into them. What you are not getting is a true ballistic computer. If you use one of the preloaded ballistic curves it will probably be close enough to get on target at 500 yards or maybe even to 600 yards. The better route is to program a custom ballistic curve using their website, download it to a micro SD card and then load that curve into the Leica.
I have used Leicas before and was impressed with the image and accuracy of the rangefinder. Not so much by the ballistic solutions. It still works better than Zeiss or Swarovski for getting your shot onto target at short to midrange.
You won't find a rangefinder that will match the optical performance of the Leica, Swarovski or Zeiss. You will also find that these Bino/LRF combos won't match ballistic accuracy of the G7 or the range finding accuracy of Vectronix LRFs. They also perform as rangefinders better than the current offerings from Leupold, Vortex, Bushnell or Nikon.
It's difficult to find a product that will excel in all three functions. If optical performance is your primary need they are great. If an accurate, long range LRF is the primary duty they are great. They are a compromise as a ballistic rangefinder. Since they do determine shot inclination, temperature and station pressure, you can use them with a good program like Shooter or Applied Ballistic or even a Kestrel with AB or Horus and overcome their only real shortfall.
I personally went with the G7 so I didn't have to depend on using a phone/app/kestrel for the ballistic solution and carry a pair of Swarovski SLC's for glassing duty.
