I've had a pair now for over a year and am pleased with them.
The rangefinder is very good indeed, I've compared it with Leica and Swarovski and I think it is better.
Very fast and reliable. Pings deer (and cows, sheep, dogs etc.) reliably at silly distances. Tree trunks, branches, fenceposts etc. also easily ranged, if necessary using the brush or bullseye modes. It will continuously track flying seagulls at over 300 yards.
Large objects, buildings etc. can reliably be ranged to 1759 yards. I suspect there is an artificial cutoff at 1 mile.
Being integrated into the binos and having good magnification means it is much easier to hold steady than a small dedicated rangefinder.
The display is bright, with a clear aim point that corresponds precisely with the laser. Its a hybrid of LCD backlit by red LED, projected into the right eyepiece. The laser is built into the left tube. There is a simple technique to adjusting the two dioptre knobs to get the display properly focussed, so don't be put off if it seems out of focus on a demonstration. Some salespeople don't seem to know how to do it properly.
The battery life is great, I've only just replaced it after 14 months and it has been played with a lot.
The ballistic calculator is very useful to me as I use estate rifles, so don't have the opportunity to learn the trajectories. It won't be perfect, but its much better than guessing. It calculates holdover in inches or cm, or MOA, based on a zero of 100, 150, 200 or 300 yards. It has a clinometer to compensate for up/downhill and displays the angle, so it can also be used for simple surveying, measuring heights of buildings etc.
Bushnell have calibrated it for a variety of factory ammo. Its not all in the manual, you have to look on the website.

As you might expect, given the price, there is a downside:
The binoculars are of midrange quality. They are based on the Bushnell Legend, but have a distinct bluish colour, due to the beamsplitters needed for the laser and to project the display.
This is not unique to Bushnell, I've noticed a similar colour cast in Leica Geovids, but not as pronounced.
For hunting use this isn't a problem, but for e.g. birdwatching it would be distracting.
Also they are not quite as bright as you would expect of 10x40, the beamsplitters intercept some of the light.
They are quite sharp, with only a small amount of colour fringing. Field of view is typical for 10x40.
I would have preferred them to be in 8x40 or 8x30 for wider field of view and better low light performance. I see they do make a 12x50 version, which might be useful for the Scottish hill.
They are quite big and chunky, and feel very solidly made.
The "rainguard" coating really does work and they are truly waterproof, I've been out in dreadful weather and never had any issues.
If you already have a decent pair of binos you may want to carry them too, to use at last light. If you haven't been spoilt for good glass you may be quite satisfied. Most of the time they are perfectly adequate.
I bought them from the Bushnell importer, at a game fair. He matched the best internet price, and threw in some freebies. He warned me that the UK (lifetime) warranty would only be honoured for official imports, some dealers were supplying "grey" imports, e.g. SGC.
If you buy at the right price I think they are worth the money.
I have read that Pulsar are soon bringing out a new rangefinder/bino at a similar price. Might be worth speaking to Thomas Jacks to find out more.
